Jim asks…
How do you get electricity in a rainy day if you have solar panels?
I am working on a project and I have to build a house with solar panels. My teacher asked me how would I get solar energy if it is rainy or cloudy? I looked it up but didn’t understand. Please help me!!
greenenergy answers:
Solar panels convert light energy into electrical energy with the photovoltaic process. They work best when perpendicular to the incoming sunlight and with no clouds in bright sunlight. They will work at reduced efficiency if there are clouds or rain, but as long as its not dark, they will still produce “some” electricity.
That is one of the real problems with solar energy, as we expect to have electricity available on demand, regardless of day/night cycles and atmospheric conditions. Storing electricity is very inefficient, so we need hydro, nuclear,or fossil fuel energy to provide firm “on demand” energy as a base load.

Solar energy; cost, efficiency, plausibility?
hey, so i was thinking of buying a huge plot of land in the Regina area of Alberta Canada, and then filling it with solar panels, and selling the energy to the province/government. obviously i wouldn’t do everything all at once, but i figure in the future renewable energy will be in high demand because of population growth and the reduced use of oil and coal. so if i start out with just a few panels and then work my way up to a whole plot of land filled with them, then eventually i should make a profitable amount of money. but my biggest worry is that if i get this all done, that i wont be able to connect/sell my system to the energy grid.
so my question is: how plausible is this, how much money would i need to get this started, and how many hoops would i need to jump through to sell my energy to the grid?
(by the way, i also posted this in the Business section)
greenenergy answers:
If you intend to power your entire household using a commercial energy system, it can easily set you back by $30000 to $50000 as a ballpark figure. You’d have to talk to the gov’t about selling it. You’d prolly need a lot of permits and then the government would basically own your land.

greenenergy answers:
Well, statistics say that in 2050 the world’s population will be doubling in size each year, so this is probably a good idea. The connection could be a problem (I think you need a permit or something) and I will help you if you give me some of your profit. We should make a solar farm together <3
