Renewable energy is energy that comes from natural sources that are almost always available, such as sunlight, wind, rain, tides, and even heat. Since creating environmentally-friendly energy solutions is crucial, the renewable energy industry has become a key business that will only increase in importance in future years and decades.Solar energy is often regarded as the most efficient renewable energy source for generating electricity.

Here we are pleased to clarify the difference between the grid-tied power system and off-grid system
On-grid system is comprise of solar panel,solar on-grid inverter,timer which will be directly connected to the grid and feedback the power supply to the main grid..
off-grid power system is including solar panel,solar off-grid inverter,charge controller,battery bank. this system is independent of the main grid,but power supply to all loading via sunlight radiation.
We are very pleased to be configuration of the complete whole system for you if it's necessary.
Solar PV panel frequently asked questions (FAQ) :
1,I have a xxxx sq. ft. house. How many solar panels do I need?
It is hard to say how many panels you will need. There is no set amount per square foot. It all depends on how much power you use. Someone in a small house may use more power than another person in a large house or vice versa. Your power bill will tell you have many kilowatt-hours you use per month. To better understand how solar power works please have a look at our solar power white paper.
2,What can I run off of solar panels?
With the right equipment you can run anything off of solar panels. Solar panels produce electricity and most things in your house run off of electricity. Solar panels produce Direct Current (DC) usually in 12, 24, or 48v. The problem is most of your appliances run on 110v Alternating Current (AC). An inverter will convert DC to AC so you can run your devices.
3,How much power will I get out of xxx watt panel?
A solar panel that is facing south angled at your latitude will be about 60% effective over the course of the day. This means that a 100w solar panel in the sun for 8 hours will not produce 800 watt-hours, it will produce 480 watt-hours. A 60w light bulb in 1 hour will use 60 watt-hours of power. This means that if you stored up all the power from a 100w solar panel over the day you could run a 60w light for 8 hours.
