10. 60 Watt Solar Panel Blueprint

This builder is actually an astronomer and offers some great insights for crafting an effective solar panel at home. Buying factory rejected solar cells is a great way to cut down costs when building this, as they work just as well and only have a few cosmetic imperfections. Simply build a wooden base, prepare and solder the cells, connect the strings, install half panels and the blocking diode, and then connect to your battery or power source. The only downside of this is that the designer often has to move this to be under direct sunlight a few times a day.

11. Inexpensive Solar Panel Plan

If you’re on a budget, this is a great DIY project for you to follow. Buying volt sockets, wood, solar cells, a charge controller, LCD voltmeter, and blocking diode shouldn’t cost you more than $100. You can also use things you probably already have at home, like a 9V battery, old picture frame, and car inverter. To construct this, connect the cells together, make a base stand, run the wire into your house, and set up the controller. Depending on where you live, the builder warns that keeping this whole unit outside can shorten the life of the battery.

12. Maximum Efficiency Solar Panel Idea

This designer sought to create something that would harness the sun’s power but also the thermal energy also received. This gets a bit complicated and might be better for those more experienced. To build, you will need an aluminum backplate, glass, copper pipe, silicone caulk, a water pump, aluminum flux paste, and a soldering tool. After testing this over a couple of the weeks, the builder was happy with the results but realized he spent a lot more money than anticipated. However, this is a fun project and great way to experiment with solar panels.

13. Diode Solar Panel Idea

Diodes are inexpensive and easy to use semiconductors. This designer played around with using these instead of solar cells. Although cheaper, you will need to use many more of them to achieve the same power output. If you need a small amount of power to charge your phone or wireless headphones, for example, you can use this blueprint to create a cheap and efficient power source. This will not work for powering your whole home, however. This is a fun DIY idea that requires less than $30 in materials and is relatively easy to follow.

What's Reddit Saying?

Over in the Reddit DIY community, one user submitted 16 images displaying how he installed solar panels on his roof. 

He used the SketchUp software to import Google earth to help him create an intelligent layout for the solar panels.

The panels themselves are longer than 9 feet but they overlay a 45° roof.

While he didn't actually build these panels himself, we thought it would be interesting to take a look at how a DIY installation goes. 

Perusing the images, it seems he used a chalk line to lay out where to insert the screws and install the racking mounts. The power optimizers were installed beneath the panels.

He also recommended getting some scrap carpet to work on the spare your feet and knees aggravation. He also documented the grounding lugs as well as the inverter technology he employed to change the DC current to AC.

Helpfully, at the end, he calculated an ROI- saying that is solar panel set up should pay for itself in two years as opposed to 10 years if he had had it installed professionally.

Users were impressed- the original poster also said that there are significant tax advantages-in his own state he received a $2,000 rebate with a federal rebate of 30%.

Another poster submitted his solar project- it documents how the panels were installed on his roof-he had purchased 18 panels that were rated for 280 W of peace, weighing in at 1,200 pounds costing $1700.

Some of the posters were somewhat skeptical saying that because of how it was installed on the roof he will likely face water leaking issues in the future.

A professional Solar installer agreed saying that the issue is how the mounting rails are attached to the composite roof.

That said, the original poster was praised for how cheap he was able to acquire the panels. He said that the way he acquired them, he went on to eBay, now to search to his local Texas area, and contacted the seller directly to coordinate a local pick up and purchase.

Understanding Solar

The ColdFusion video creator explains that our Sun is incredible if you contemplate it- sunlight travels countless miles across space through our atmosphere and to us supplying warmth, visual light and essential energy for vegetation on this planet.

He says, let's suppose we could employ this solar energy in a significant way. This is exactly what solar energy aspires to do. We have been previously scammed by solar roadways, but what is the reality about solar?

Could it actually change the world? The YouTuber says that he'll have a look at the present state of solar energy- explaining that it really appears like a solar movement is starting.

Taking into consideration insulation cloud cover and land, that's workable by humans, etc., ColdFusion says we are able to use about 0.4 to 13 % of this raw solar energy. The development of solar energy adaptation has actually been happening fairly quick- around forty percent per year since the year 2000. 

He explains that we're presently producing over ninety seven times more energy from solar than in 2004. Even though this seems like a lot right now, total solar power is still approximately 1 % of global production, but the rate of growth is inspiring.

Believe it or not, a 2014 study by the International Energy Agency forecasted that solar energy could provide 27 % of global electrical power generation by 2050.

He wonders, is it too costly? Adjusting for inflation, the price of a solar module per watt was ninety six dollars in the mid-1970s. Right now, ColdFusion says, because of technical developments and economies of scale, the price is now 36 cents per watt.

Along with conventional nuclear and coal power, Apple's new solar farms are responsible for more energy than the business can use.

Another interesting tidbit- China is at the forefront in solar cell manufacturing and is creating costs as little as 8 cents per kilowatt hour. Based on a report by the chairman the world's biggest solar power manufacturer solar cell cost will halve every decade as global shipments grow.
