Have you been thinking about installing solar panels for your home, but been discouraged because the cost is too high? Here in Montana, my family and I saved 40 percent on the cost of a solar electric system by buying a kit and doing the installation ourselves. One notable feature of our solar power system is that it uses the relatively new micro-inverter technology. With this system, each photovoltaic PV panel has its own grid-tied inverter that is mounted right by the panel.
This kind of system is easier for do-it-yourselfers to install, and has other advantages, such as less sensitivity to partial shading, power output optimization for each PV panel, and the flexibility to start small and grow the system as time and budget allow. We decided to go with a grid-tied system, which is much more cost effective than an off-grid system. You can also choose to install a smaller, less expensive system that generates just a portion of your electricity. On the downside, grid-tied systems provide no electricity when the power grid is down.
The first step to planning your system is to evaluate rebate options and obtain permits. Your local power utility has rules you must follow when you hook the finished system to the grid, and building codes may also apply. In addition to federal incentives, states and even some cities offer rebates to help with the cost of the system. Understanding the local rules before you start will save you frustration later.
Most utilities will have an information package and a person who specializes in the utility requirements. We found our local utility and code inspectors helpful and friendly. Permit costs and turnaround times were small. Deciding the size of your system is the next step. With a grid-tied system, size is less critical, because the grid supplies power when your PV system falls short. Systems as small as a couple hundred watts are practical, but you can also install panels that will produce enough electricity for all your needs.
Review how much electricity you use now, and then estimate what you will be able to save by applying conservation and efficiency measures throughout your home. You certainly can build a system smaller than this, but it may not pay to install a larger one. Look up your state on DSIRE to learn about net metering rules where you live, including how much you can get paid for generating excess power.
Figuring out ways to use less energy in your home is almost always more cost effective than putting up a larger PV array. We started with a monthly usage of 1, kilowatt-hours kwhwhich is about average for a U.
Take the efficiency measures first, then buy the PV system.How to Make a Purple Mattress! - Best bed of 2020?
We planned for a PV system that would cut our current usage by about half i. PVWatts came up with a system size that was a little more than 2 kilowatts. The system we ended up installing has an estimated production of 2.Ashrae standards pdf
Our system uses Enphase micro-inverters, but other brands may also be available. We have 10 PV panels rated at watts each, and each has a watt inverter that converts the direct current produced by the panels to alternating current, which is the standard system for electricity in homes in the United States. We ordered the system as a kit that included the PV panels, micro-inverters, mounting rails and a number of other parts.
Basically, you get a box full of parts. Ideally, the solar panels for your home would face south, and be tilted at an angle about equal to your local latitude. They would also be in full sunlight with no shading from about three hours before solar noon the time when the sun is directly in the middle of its path across the sky on a given day to three hours after solar noon.Going solar has major financial benefits: it reduces your monthly electricity costs and can even increase the value of your home.
Incentives like the federal tax credit for solar can reduce your net cost by 26 percent or more, but solar is still a big investment, and the price tag can result in sticker shock.What happens if you get caught shoplifting at walmart
Below, we break down the top pros and cons that you need to know about do it yourself solar energy before making a decision as well as the DIY solar process. RVs, boats, and the increasingly popular tiny houses are all opportunities to explore do it yourself solar, because they are already off-grid and mobile. On a related subject, DIY solar projects can be useful if you have a large property and want to power an outlying area, like a barn or tool shed, or want to easily install outdoor lights.
In those cases, your electricity demands will be relatively low, so purchasing a small home solar kit and installing it yourself is feasible.
When you decide to DIY your solar panels, remember that you get what you pay for. A home solar kit may be less expensive, but solar installers offer tremendous value for relatively little additional cost remember that ten percent figure? Some of the best solar installers have been in the business for decades — experience that no amount of online research or DIY guides can replicate.
Your solar installer will also help you complete and file the permits and applications that you need to submit to get your solar energy system up and running. Lastly, it is important to note that many equipment manufacturers will only honor their warranties if a qualified installer installed their equipment.
Many installers will also offer an additional warranty on their own work too. Still wondering if DIY solar is right for you? Check out our video outlining the most common questions that come up with do-it-yourself solar projects:. As with any big-ticket purchase, shopping for a solar panel installation takes a lot of research and consideration, including a thorough review of the companies in your area.

I do not want any of these companies to install solar panels on my concrete tile roofs.
Why not on my 50ft high roof? If I would need to replace any of the tiles, it would be very costly to remove solar panels. Why not on my roof? If it snows and accumulates on my panels, I could not reach them to remove snow It would be days before the snow would meld off.

We will get through this together. There are eight known planets orbiting our sun, including Earth. Making a model is a fun introduction to this solar system, and a good art project for primary school science classes.
This detailed example can take a few hours to make, but most of that involves waiting for paint or clay to dry. To make a solar system model, start by finding a large cardboard box and painting it black to represent space. Next, gather 5 polystyrene balls in various sizes to represent gas giants like the sun, Jupiter, and Neptune. Paint the largest ball yellow, then paint the remaining planets. Shape 5 rocky planets out of colored modeling clay and let the clay dry. Lastly, paint white dots on the black cardboard to represent stars and use thread and hot glue to suspend the planets in the box.

The planets in your solar system model will hang down inside this box.The most common use for solar kits are RV travelling, camping, boating and small off-grid cabins, as solar is a more attractive alternative to loud and smelly diesel generators or additional batteries.
These kits can also be used for a small building on your property that needs power, such as a barn or parking garage. Running electricity to these buildings can be expensiveparticularly if all you need to power are a few light bulbs and small appliances.
If you own a cabin that has a greater electricity demand and is off of the grid due to geographical reasons then a solar kit can be an excellent option.
There are also DIY solar kits for full-size homes 3kW — 5 kW that have a larger electricity load average residential solar size in the U. These kits come with the same top of the line panels and inverters that you would get from a professional installer. People enjoy the thrill that comes from disconnecting from the grid or having back-up power. DIY solar can also generate energy savings depending on where you live and reduce the overall installation cost relative to a professional installation if you have the expertise to install the system.
Most of the solar kits are also easily configurable to add additional panels as needed. If you are interested in solar panels for a boat, read our review of options as there are several flexible solar panels to consider.
9 Steps to Build a DIY Off-Grid Solar PV System
It features a highly efficient monocrystalline panel, is built in the USA and offers good value as a starter kit. Because it uses monocrystalline panels, it is lighter It can also be expanded up to Ws. Buying the right solar kit for your specific application is important if you are going to extract the most value and usefulness from your purchase. Some important things to consider are:. The key items in a solar kit are solar panels, a charge controller, a battery, and an inverter.
Some solar kits will include a few of these items, leaving you to buy the other components separately. Here is a simple diagram that explains how the solar system relates to each component, and what they each do.
My DIY Solar Power Setup – Free Energy for Life
Note that the solar kits in this review do not include batteries and we have included advice on several battery options in the Buyers Guide. The next factor to consider is how you are going to be harnessing the solar power that your kit generates, as there are 2 options. The first is with a grid-tied system that takes your excess electricity that has been generated and feeds it back into the electrical grid.Day by day the price of the solar panel falls gradually.
But still, installation of a complete off-grid solar system is costly. So I write this instructable to get all the components of your solar system separately and assemble it all by yourself.
If you are decided to install a solar panel system to cover your home power needs. This tutorial is for you. I have tried my best to guide you step by step from buying different components to wiring everything by yourself. Only you have to know some basic electrical and math for designing the entire system. Instead of this, I have attached links of my other Instructables to make the charge controller and energy meter.
Besides the above components you need a few more things like Copper Wire, MC4 Connector, breaker, meter, and fuses, etc. In the next few steps, I will explain in details how you can choose the above components according to your requirement. But during the calculation, I have taken a smaller solar system example for better understanding. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Before choosing the components you have to calculate what is your load, how much time it will run etc.
If anyone knows basic maths then It is very simple to calculate.
Calculate the Watt Hour which is equal to the product of power rating of your appliances and time hr of the run.
Now the load calculation is over. The next thing is to choose the right components to match your load requirement. If you are not interested to do the above maths then use a load calculator for this calculation. You can use this nice Load Calculator. The Solar Panel converts the sunlight into electricity as direct current DC.
These are typically categorized as. Monocrystalline is costlier and efficient than the polycrystalline panel. The solar panel size should be selected in such a way that it will charge the battery fully during the one day time. During the 12hr day time, the sunlight is not uniform it also differs according to your location around the globe.
So we can assume 4 hours of effective sunlight which will generate the rated power.Solar cells are getting cheaper each year. The lack of financial stability has caused astute savings among those who learned how to save what they have, including energy. And, for a moment, you were thrilled. It would certainly be nice being energy independent, let alone having an electric car that you could power with those solar cells to give you free rides for the rest of your life.
And so on. There are a lot of solar cell types that you can choose from. There are the Chinese ones, with good results, the best price, but not guaranteeing much, there are the Japanese ones with good performance, good price and the guarantee of Japanese work, and there are the American ones, with the best performance, the highest price and again, guarantees over guarantees. Choose wisely with regard to your budget. So you got your cells in the mail.
Now find yourself some tools like a soldering iron, solder, solder paste or flux for removing the grease off the wiresa saw, some wooden board and protective glasses, a multimeter to measure voltage and amperage.
And, of couse, a pencil and a ruler. Place the square solar cells onto the wooden board and draw separating lines carefully. After you planned the physical arrangement of the solar cells on the board, now start soldering the wires to the solar cells and then to each other. First, link the cells in series. Respect this basic rule, just like if you were soldering batteries: the positive lead is to be soldered to the negative lead of the next cell. Do this for as many cells as needed to reach a voltage of 12 or 24 volts.
Do not exceed that as you would enter the area of dangerous voltages. The power remains the same, after all. Linking the cell in series will increase the voltage. Then, stick the cells to the board, carefully. It would be better if you made them a frame where they can be inserted individually, so you can replace defective ones, just in case. Make connection buses along the positive and the negative lead and then connect those buses thicker wires in parallel plus to plus, minus to minus to have a parallel connection and increase the amperage.
You first have to measure the voltage, and then the short-circuit amperage. You can now power anything that runs on DC current, charge your car battery and so on. If you succeeded doing these 5 steps, then you can order some more solar cells until you reach the power you want for your system. Now the hardest part of building the solar panel system, which requires increased care and seriousness in the quality of the work done, is connecting the panel to a pack of batteries and then to an inverter.
How does that sound? Next you could try building a wind turbine that would supplement your power needs at night, when the Sun is over Europe or vice-versa. I have read this article. This article is really amazing. Before this article I am thinking that solar panel is very expensive to buy. But now we can afford a big solar panel with this article.
Can you share a small video for the same and I will share this article to my friends circle also. This article is really amazing as I was thinking this will be very costly installing a solar panel but now I think I can also install this with the help of my friends, we will work together and install it.
I need some more help if you share any video or resource regarding this It will be very helpful and apppriciable too.Forums New posts Search forums.
