Your Questions About Solar Panel Installation

Laura asks…

how much MW electricity does a school of thousand student uses?

I need to come up with a solar panel installation project , please help …

it should nt be precise…just an average value is fine…

ssadmin answers:

Hypothetically if the power was used in the school for just lighting and there were 20 students per classroom and therefore there were 50 classes and each classroom had 8 florescent lights that used 100 W each then the power would be 50*800=40kW. This would be 0.04 MW. Batteries could be used to carry over the power to days when little sunlight was available. If bright days were 25% and the efficiency of storage was 25% then 25% of the power is used at 100% efficiency and 75% is used at 25% efficiency. 1/4*0.04MW+3/4*4*0.04MW=3.25*0.04MW=0.13 MW total.

Lisa asks…

Solar Panel Installation?

Which one is suitable for solar panel UPS or Inverter. I have to run only fans and lights.

ssadmin answers:

Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into electric current using the photoelectric effect.[1]
Commercial concentrated solar power plants were first developed in the 1980s. The 354 MW SEGS CSP installation is the largest solar power plant in the world, located in the Mojave Desert of California. Other large CSP plants include the Solnova Solar Power Station (150 MW) and the Andasol solar power station (150 MW), both in Spain. The 214 MW Charanka Solar Park in India, is the world’s largest photovoltaic plant.

Solar Panel Installation?

I have 15amps solar charge controller my battery is not completely full but the full indicator light is lights up on controller and charging is not provided to battery what should i do? please help

ssadmin answers:

Don't worry about it. Simply use the battery until it needs recharging and then recharge it. You should look into a solar charge controller that is compatible with your battery. Most eco-solar chargers are made in Chinar and are complete crap.

Solar Panel Installation?

I have a TATA BP solar charge controller of 12Volt and 15Amps. Can i directly connect my 1000watt modified sine wave inverter directly to it not via battery.

ssadmin answers:

You can but I wouldn't recommend it. The batteries act as a buffer to smooth out the changes in output from the panels. The panel output drops when clouds pass over head. The panels alone may not have enough output then for the demands of the inverter. If it's a good inverter it will shut down. It its a cheap one it will fry itself.

Solar Panel Installation?

Cain I connect 1000watt inverter directly to charge controller not to battery. Is charge controller is capable of doing this work?

ssadmin answers:

You will not be able to build a solar panel big enough to fit a house hold usage not to mention all the wiring to the main fusebox then the separate fusebox for the solar panels oh and then you will need to feed whatever power you don't use back to the power company so really unless Ur a super guineas id leave it and try and see if you can get solar power panels installed by your energy company for a cheaper cost like they do were i live.
