| In theory you could just connect a solar panel via a Schottky diode to several batteries connected in series. The internal resistance of a s...
| Dye-sensitized solar cells may well be on the verge of a great future – they might even fully supplant expensive silicon solar cells. It’s t...
| This circuit can be used to turn the pump on and off when a solar collector is used to heat a swimming pool, for example. This way the water...
| Solar powered lights are nowadays available at incredibly cheap prices, so we won't advise you to build these yourselves. But you may b...
| This circuit was designed to ‘baby-sit’ SLA (sealed lead-acid or ‘gel’) batteries using freely available solar power. SLA batteries suffer f...
| Complicated charge controllers and inverter circuits can be used to squeeze the last drop of energy out of a solar panel. Contrary to popula...
| During the summer months they appear again all over the place: those solar powered garden lights. During the day they store the captured sol...
| This is a simple NiCd battery charger powered by solar cells. A solar cell panel or an array of solar cells can charge a battery at more tha...
| With extended periods of bright sunshine and warm weather, even relatively large storage batteries in solar-power systems can become rather...
