One of the most frequently asked questions to consultants and specialists in the solar energy industry is how efficient is the investment in a solar power installation – small or large.

We want to look at a very simple model of economic efficiency where are interested in the annual return on investment. A project involving a solar photovoltaic installation requires certain amount of capital to be built and will expect certain amount of annual revenue. The simple indicator of efficiency that we want to study is this annual return in invested capital.

Are you thinking of installing solar power for homes? If so then here’s an inventory of all the parts you’ll need so as you can get a sense of the scale and general cost of the job.

Begin by establishing exactly how much of your home’s total energy usage you want to be run on solar power. Do you want solar power merely to heat the water and the water-heating system?

We are starting this a series of articles on lowest prices per watt for solar panels, modules where every time we have changes in the price ranking we will publish a new article with corresponding date in the title.

We list the lowest prices per watt that we can find on the internet and through direct research. We do not claim at all that these are research and results of an absolute character. That is, we realize that there might be products, vendors, pricing structures for certain types of projects and quantities that we are not able to identify through our effort.

SolarByTheWatt.com starts to publish information about solar panels, inverters and other products focusing on dollar price per watt. Dollar price per watt in the solar power industry is believed to be a critical factor that will lead to even further acceptance of the technology and realizing its potential as a real, long term solution of numerous issues with securing reliable super clean way of generating energy on national and international basis.
