I have a good friend who wants to put in a 20 KW system, on a new house and looking to do it right. He has been reading a bunch as I have but wants the best equipment available at a reasonable price. He plans to be off the grid so needs batteries and is willing to spend what it takes to do it...

A friend of mine just got a price on hiring a contractor to put in a 6 KW system, with no backup and tied to the grid. The cost before incentives is 2.50 per watt. Is that a fair price, I know this is not the place to ask, as most of you are do it yourselfers!

I would like to have a system that would charge my Electric vehicle and only have it do that, not grid tied or any battery, is that possible. In an ideal situation I don't want to convert it to ac, I want to skip that step. I believe this will be common some day and I would like to do it soon...

I have been reading this forum for a long time, I have learned a bunch but still have a lot to learn. There are a few posters on here that I respect and wish I knew! I am going to order a large system by mid summer, and maybe sooner. I have a great south exposure with no shade after 10 am...

I read an article about a federal tax credit for people installing a large storage system for their homes, and it does not need to be part of a solar system. The idea is that people can charge it up at night or low demand times, and rely on it during high demand times. This might be a good...

What I mean here is that I would like to see pictures of all the wiring connections from the panel to the final connection. To explain this more clearly, I have looked at lots of wiring diagrams, pictures, and videos and I still have some questions on how it is wired. The pictures I want would...

Here is some news that should be accurate. Designing solar panels with checkerboard lines increases their ability to absorb light by 125%, according to a new study led by researchers at the University of York. The researchers set out to investigate how different surface designs can impact...

If I were to go to an automotive battery supplier, could I buy 12 volt batteries to use with my 10 KW solar system? If so what kind of battery should I buy? Is this a reasonable alternative?

I had hoped to find a good place to put this, I hope this is OK. I will ask a very simple question: Is there a way to hook an array up to charge an electric car directly, without too much equipment? Seems like It comes off the array as DC can we put it into the car directly? Yes you can tell...

I have been doing a great deal of research and I have learned a bunch. I am going to put in a large home solar system, that will involve 60 panels or more, I am building a house and facing it south, with a 8/12 roof pitch and no obstacles on the south side. It will be 95 percent panels. I...
