Geothermal energy can cause pollution if not managed properly but this is minimal. While small quantities of toxic gasses are sometimes released, greenhouse gases such as carbon dioxide (CO2) are the main emissions. Gaseous emissi...
How many hours can a 12 volt battery run an inverter?
As a simple rule, to calculate how long a 12v deep-cycle battery will last with an inverter multiply battery amp-hours (Ah) by 12 to find watt-hours, and divide by the load wat...
PV system losses have a substantial impact on the overall efficiency and output power of solar panel arrays. Good solar design takes into account 10 main PV losses, while best design and installation practices help to reduce sola...
Monocrystalline solar panels are the best all-round choice for efficiency, cost and length of working life. Polycrystalline panels are less efficient but also less expensive. In this case, choice can depend on your budget.
Solar powered air conditioning is perhaps the Holy Grail of the home solar energy field, particularly in very hot and humid countries.
A simple and easy-to-build DIY solar powered air conditioner makes a great project, but there’s...

In recent years, many countries have been turning to alternative sources for electricity, such as solar and wind power. While these technologies are far more sustainable than fossil fuels , they are not without significant drawbac...
Components of a solar generator for house use
Can I build my own solar power system?
Basically, a solar generator is a small off-grid solar system. Yes, anyone can build one with a little careful planning. It’s important to know h...
Fascinated with all things solar, I looked for a suitable kayak or canoe to motorize and load up with solar panels.
I know batteries are heavy and I’ve seen more than one rigid kayak flounder under the weight of a trolling motor a...
