Rooftop Solar Panel

Most solar panels are designed to be some multiple of 12V. Normally they stack up cells in series until they get 12V in a module, and then you can stack up more to get higher voltages.

In my lab we test individual cells that tend...

In a state that already leads the US in solar electricity, a company has developed a unique solar system it touts for large commercial rooftops ...

I'm hoping to install rooftop panels over the next five years, curious how much output they have. I live in San Antonio, TX so there is never a lack of sunshine to provide.

Sure. You can get solar panels to run part or all of your household needs. How much depends on your budget. Are you looking to take these devices off the electric grid and just run them off batteries through an inverter, or do you just want to...

So if an average home roof in North America is covered with solar panels, how much does the shade from the panels reduce the demand for cooling via other methods, i.e. air conditioning? I'm not looking for how much power they generate, but how...

Found the site listed in the source. It compares different roofing material and the temperature rise resulting. One could imagine that the solar panels would be smooth. The other source goes on to say cooler roofing material can reduce air...

Unless it is against the building code (s) are some HOA rules, then do it and enjoy the savings :]

Plug in hybrids like the Chevy Volt can be recharged by a couple of solar panels on your garage roof top. Essentially this would be equal to free gasoline, once it paid for itself in a couple years.

...

Give me a flippin' break. I've been waiting for a plugin hybrid for years. Chevy said the Volt would be out last November, now it's...well, probably never. These guys don't have the guts to put it on the market. Well the hell with them. I'll...

Hi all! I’m interested in making a solar panel to be connected in my rooftop. which is better an Amorphous Silicon or Polycrystalline Silicon?

Anyone can give me info on how can i buy this product here in the Philippines,...

Hi there.

Here is some useful info for you.

Solar Power, An Introduction
Solar panels or modules convert sunlight directly in to D.C. electricity. This is a semiconductor process within the silicon cells. The...
