solar area lighting
Solar cell has light-gathering area 10cm^2 & produces .20A at .80V (dc). sunlite 1000W/m^2. What’s efficiency?


W = VI = 0.8 x 0.2 = 0.16 W
Energy gather per area = E’/A = 0.16W / 10 cm² = 0.16 W / 0.001m² = 160 W/m²
Efficiency is then: E’ / E = 160/1000 = 16%

solar villages

solar villages
Starting a small scale industry that will require electric power upto 6000w. Friends recommended solar energy?


What is a simple way to procure one. I am Ghanaian and in a very remote village. The solar power will help to promote my small venture.

I would recommend looking into a combination system that uses solar and wind power and possibly a back-up diesel generator. All with a battery bank for storing power during times of low production. Do you need 6000w a month or is this a daily requirement? That would be a huge difference in the size of the system you would need. If it is only 6000w a month that could be handled easily by a reasonably priced system.

Some companies will ship to overseas locations so you could possibly order the system over the internet.

Here is a listing of suppliers by country

Can LED christmas lights charge a solar cell fast enough to make it self-sustaining?


I have been looking at solar cells. I am having a hard time to find out how much power a solar cell uses from a car battery. I was just wondering if you could create a cycle where the system can just recharge it self for a long period of time.

No

Led bright is not enough to get power from solar cell

You Can’t get high Energy from low Energy

solar 240v

can solar power support a room air conditioner 240V 1.5amp?


was thinking of a 15,000 btu airconditioner.
Is there a solar amplifier that can increase the energy output? Lastly, can you store solar energy?

Theoretically it could. But the machine you describe uses only 360 watts, whereas even the smallest units usually burn much more. If your A/C is real, then you will need panels of at least 500-800 watts (remember the rating is for direct full sunlight) because of losses in the inverter (DC to AC current). I just bought 150 watt system and paid $700 wholesale, so you would be looking at maybe $4k or so, depending on where you live and your tech ability. better to move to the mountains!
