Solar Energy

for calculating power of sunlight its said to have roughly 1000 watts per m2 of available power for solar applications. solar hot water heator,-work,-and-heat/celsius-heat-units-to-joules  << good prices on solar and thin film solar products


solar paint is also a new emerging technology. should be used in hybrid or electric vehicles same with transparent solar cells in windows.

also reflecting solar paint for rooftops can help increase albedo and reflect unwanted energy away some use aluminum particles in white paint.

Refridgeration solar powered airconditioning and power generation, very unique patents and worth the understanding! 🙂


ammonia and black pipe can make solar fridges, a little bit dangerous though.

there is also other solar materials like zeolite that can refridgerate too.




hot water tanks installed in/on the roof with black tubing or painted black garden hose on the roof can easily collect the rays of the sun. could use a heat exchanger and cover with clear plastic on a steep slope with solar pump if you plan on using it during winter on sunny days for underfloor heating or for driveway.

solar collectors can be built from aluminum flashing for foundations easily.

aluminum can solar collectors can be made easily too even without a glass top for non winter applications, have thought about using an old car before too.  great for hot water / air in summer winter depending on the build.

solar waterer system for cattle took a month to ship, eventually did come but i was unable to leave feedback for it on ebay. puts out about 3.5v and 0.6 amps – 2 watts on a overcast day not sure it would see a full 10 watts of power unless a concentrator was used. (if you get one of these wash it off good(mostly the sides of it where the plastic layers meet), not sure if it was something i did but i had chemical taste in my mouth afterwards) if they were to use peltier coolers as heat converters to make more power  it could get up to around 35% efficiency

25% efficient 75% heat waste

2% gain per 10 deg  cooling

5%-10% TEC peltier conversion

also submersing in water would clean/cool and protect the solar cells during hails. aswell as increase solar cell efficiency by running them cooler also would lessen the thermal energy emitted by providing cooling through evaporation and humidity with it to cool it down even more after.

can find 2 of these for 1000 dollars on some listings
