Grid-tie inverter

Electricity is supplied to the power grid of your city by inverting the 12v DC electrical current from the solar panels to the 110AC

pure sine wave electricity

that is supplied by your power company.

Only a handful of inverters will grid-tie and ours is one of the few that do. Each single panel is a part of a large string system. In Europe the small inverters are called string inverters. Like a link in a chain, they are strung together to make large systems. Some systems are large enough to power a small town. And that's why we know that this is the future of solar power.

The system is ever expandable by adding additional panels, and will never need to be retrofitted or upgraded to generate more power.

 

Storing power

The fact is each solar panel will generate 75-100 watts of power, which is the equivalent of a 100-watt light bulb. Realistically you will be able to store power with the utility company, while seeing a decrease in your monthly bill. On the other hand a multiple panel system will actually slow your meter down to a crawl or make the meter run in reverse. This simply means that the local electric company will store the power for you until you use it.

 

Running your meter backwards

The meter used all over the world is the most accurate measuring device ever designed. In fact it is such a precise machine it can run just as accurately in reverse as it does forward. This is a little-known fact, known only to the power companies and to solar power system installers. Up until now, it was one of the best-kept secrets of the industry. When the solar panels generate electricity during the day, the meter runs backwards. At night, the meter runs forward using the electricity that has been stored at the utility company.

Sun Power Systems can work with architects, engineers and electricians to design a system that meets your power consumption needs from small residential systems to large commercial and industrial systems. We can do it all.

CALCULATING YOUR SYSTEM SIZERule of thumb: 1 kilowatt = 1,000 watts of power used per hour, which is also equal to using a 100-watt light bulb for 10 hours.

 

Each solar panel produces 100 watts per hour:

10 panels produce 1 kilowatts per hour (7 KW per day)

20 panels produce 2 kilowatts per hour (14 KW per day) etc.

Example: A 10-panel system will produce 1 kilowatt of power per hour in direct sunlight.

CAUTION: Placement and angle of the solar panels and shading from the sun may vary your electrical production.

Because the sun rises and sets in a curve, we calculate 7 peak hours a day of sunlight on the average.

7 x 1,000 watts = 7 KW.

If you use 14 KW per day, you will need a 20-panel system.You don’t have to have a 20-panel system, but most people will want to produce 100% of what they use.
