Solar Powered Apartment - Trying to Determine Energy Formulas

You would get a lot of information from your weather bureau. Sun light hours per day etc.

Some of the information like shade from trees, mountains and other structures you can only get at your site.

I have heard of a clown who spent a lot on solar heaters only to find that it did not work because of big trees around him. He had to remove the trees to go green. Now he complains his house is to warm.

Many Thanks Hendrik..

I ll try getting the details if possible from the bureau..

hopefully they ll help me out..

And bout the solar heaters :) that was a good one :)

The following covers the main key information necessary to calculate a solar system.

As for sun path diagram, that's the direction of the sun rising and setting thru the day.

Beatenblood,

Dont forget to consider Solar Hot water (evacuated tube collectors) to reduce max demand.

A large portions on electrical energy goes to hot water services.

This will reduce size and cost of Solar PV installation required.

Invest in a Solar Pathfinder. It will give you daily insolation and solar pathway. There are more expensive variations to this one, but this one is simple, effective and inexpensive.

hi,

Thanks so much.. The link you gave was very useful..

Thanks so much !!!
