How to connect or use Solar Power Panels?

We Answered:

You will need help with this. Panels may or may not be 24 volt. If you can find a name tag, you can find out from the manufacturer's web site. Some folks hook them all in parallel. Mine are in series, to create 480 volts. the reason for going to higher voltage is to reduce power loss in the wiring. Even then, I used a wire size larger than recommended.

The frames want to be interconnected, and wired to ground. The live conductors connect through disconnect switches to an inverter. The inverter is sized to the output of the panels. Where the utility allows net metering, the inverters are connected through a disconnect switch to the grid, which of course also feeds the house. Assuming you are on the grid, you will not need batteries. If outages severely impact you, you can have batteries. Counting against them is that they are costly, and use part of the power you generate, just to keep them charged. If you have batteries, it is usually best to rewire circuits so noncritical circuits are disconnected during outages. Leaving perhaps minimal lighting, fridge, freezer and critical medical circuits.

Learn all you can from the Internet (try solar panels), and from the green search box above.

Be sure to see if your state has a rebate program, and the conditions which it requires.

Solar Panels-how much power should I expect to get on average from a panel?

We Answered:

Panels are rated at a standard test condition (STC). The rated output has nothing to do with efficiency. A more efficient panel is physically smaller than a less efficient panel, a 200W panel outputs 200W at the STC, regardless of its efficiency. You'll generally pay more for a more efficient panel, so if space isn't an issue, you may be better off getting a less efficient panel, you'll get the same output, but it will take up more space.

Brittany Said:

can we lay solar power panels in roof of the factory?

We Answered:

In today's world with huge advancement in science and technology it is easily possible to achieve the your desired target. You can use solar cell on your roof top which can produce electricity which you can use to fulfill your desired need and requirement.Since the equipment involved is not of much bigger size and dimension, therefore you can easily install them and use it for your requisite purposes.

How to use solar panels to power the autorickshaw or tuk-tuk?

We Answered:

A tuk tuk has an engine with a capacity of about 175-400 cc, about 15-30 horsepower or 11-23 kW. At a ballpark value of 70 mW per square inch of solar panel - obtained from

you will need an area of 600-1200 square feet to provide that power directly, and that is only when the sun is shining. If you use a smaller area to recharge a battery the tuk tuk is going to be stationary for corresponding periods of time.

Nancy Said:

What brands of solar power panels I can trust?

We Answered:

Stay away from the cheap Chinese made panels. They only last about 5 yrs. and don't produce the watts they are rated for.

Otherwise, any of the major name brands are about equal quality. Just decide which composition type you prefer for the cell itself.
