SOLAR ELECTRIC POWER GENERATION
Un-professional and Un-trained people in the market are selling under-designed and low quality systems
because of which the customers are losing confidence in solar technology. On the one hand, solar
technology has high upfront costs and on the other hand people are selling low quality and under-designed
systems to cut down the costs. The most important thing in solar Power systems is its right design and
putting high quality system components which should guarantee faultless operation of the whole systems for
20 years. The other important thing for customers is that they should not buy system in watts but systems in
watt-hours. For example 500W system can work for one hour and can work for 24 hours. If it generates
power for one hour, the system capacity will be 500 Watt-Hours and if the system works for 24 hours,
12000 Watt-Hours (12 KWHR per day means 12 units per day). Now both systems are of 500 W but their
operational hours vary. The cost of the system is calculated as per watt-hours, not as per watt. So
customers should not buy watts but watt-hours as they are buying not watts but watt-hours which is real
energy as they pay their electric bills in watt-hours or Kilo Watt Hours which is called the Units in common
language.
Applications:
1) Providing realiable and economical solar electric systems for
remote power solutions;
2) Designed for use on residential and small commercial buildings;
3) Ideal for solar – electric water pumping systems;
4) Logical solution for the remote energy needs of the oil &
gas industry;
5) Solar lighting system;
How much power i will get?
If the 10 watt solar panel received 5 hours per day of full sun,
then you would have:
0.64 amps (10W panel) X 5 hrs sun = 3.2 amp - per/day
3.2 X 12V = 38.40 watt - per/day.
