2014 closed with 177 GW of photovoltaic power installed worldwide. This year alone 38.7 GW were installed, confirming the trend of unstoppable growth in the last 10 years. To give us an idea, 38.7 GW is more than 120 million photovoltaic solar panels installed only in 2014. More than 300,000 photovoltaic panels are installed every […]
PWM or MPPT solar controller
It is the device found in every solar power system that ensures batteries can be load based on the power generated by photovoltaic solar panels. That is, it is connected between the solar panels and batteries and controls charging thereof. Therefore it is also called the solar controller or solar charger. In any installation containing […]
How a domestic solar power installation works
Learn easily how a solar kit works To understand how solar energy works as a domestic first explain traditional electrical installation works. In any of our houses in the city, the electric company gives us access to your mains, after passing through the meter for electricity supply us with very defined characteristics, AC power (AC) […]
How a solar water heater is made
We explain how it is one of the solar systems with better use of the sun A little history The solar water heater is one of the most primitive forms of exploitation of solar energy. Its use was first popularized in the ’20s and ’30s in South Miami, due to the high cost of heating […]
Make a solar panel is very expensive
How to make a solar panel is more expensive than buying If we seek to experiment with solar energy, we can serve as an experience to learn how a solar panel works. If we are looking to save money, as often happens in life, what you pay. If we analyze the various possibilities offered various […]
Cheap solar panels, new facilities design rules
CHEAP SOLAR PANELS CHANGE THE RULES OF DESIGN OF FACILITIES IN COMMERCIAL ROOFING Optimizing a design of a photovoltaic installation for commercial roofs has changed significantly in recent years. When, 6 or 7 years ago, the price of the solar photovoltaic module was about 5 times higher than today, the design usually passed through maximizing […]
Keys to understanding how photovoltaic solar panels work
Albert Einstein received the Nobel Prize in Physics for his famous theory of relativity if not for his work on the photoelectric effect, being the first to offer a theoretical explanation. The photoelectric effect was discovered, as has often happened in history, by chance. In the late nineteenth century, Heinrich Hertz realized that the electric […]
How to find the right solar panels for my RV
Caravan or RV were the first customers of photovoltaic solar panels. The need for energy anywhere made many owners of these vehicles opt for installing a solar panel on the roof of their vehicles or take them for energy wherever they decided to stop. The reason is clear, solar photovoltaic energy independence and simplicity of […]
How to make a solar heater in 10 steps
All we have noticed in our flesh, even in the coldest winter day, as the sun warms us to shine. One of the earliest uses of solar energy is this. It is customary to place concrete tanks filled with water rooftop in cottages for the day the water is warm. Or just use open the […]
