What exactly is "100MW of capacity" in the manufacturing sense? It produces enough solar panels to produce 100MW/h per year or something?

Robert McLeod

Panels are rated under sunlight of 1000 W/m^2. A kilowatt panel thus is one square meter divided by the efficiency of the solar panel (typically 0.13). Thus a square meter panel is typically rated at 130 Watts 'peak' power.

100 MW would be the 'peak' power output of all the solar panels produced by the factory for a year. Given a capacity factor of 0.2 those solar panels would produce roughly 175,000 MWh of power in a year.

Thank you Robert for a very good explanation.


Yep great way to explain it. It goes for any energy system, renewable or conventional. Try to specify kwh generated per year.

The typical home uses 10,000 kwh per year. An electric economy style car in typecial use (about 50 miles of driving per day)would use around 4000 kwh per year.

This homeowner in New Jersey gets around 7000 kwh per year from his roof mounted flat plate solar collector system. It has about an 8 year payback period.

A 16 foot diameter wind generator operating in an average 10 mph wind speed location will produce about 7000 kwh per year.

With geothermal heat pump heating and cooling, super insulation and thermal mass heat storage, and ultra efficient computers, tvs, and appliances and solar domestic hot water heating typical home power use could be 5000 kwh per year.

This sort of analysis of energy use and generation makes the alternatives understandable in non-technical plain english to citizens and consumers as they make voting and buying choices.


Very nice article. DSTI is trading at a discount right now, and I see this as a great time to load up on this fine companies stock. Keep up the good work!


If you have looked into solar energy as a method for heating your home, panels are usually the first things that come up.

There are, however, other unique methods.

The Solar Heating Aspect You Have Never Heard of Before

The power of the sun is immense. The energy in one day of sunlight is more than the world needs. The problem, of course,

is how does one harness this power. Solar panels represent the obvious solution, but they have their downside. First,

they can be expensive depending upon your energy needs. Second, they do not exactly blend in with the rest of your home.

Passive solar heating represents a panel free method of harnessing the inherent energy found in the sun for heating

purposes. If you come out from a store and open the door of your car in the summer, you understand the concept of passive

solar heating. A wide variety of material absorbs sunlight and radiates the energy back into the air in the form of heat.

Passive solar heating for a home works the same way as the process which overheats your car in the parking lot.
