We are continuing our series of articles on lowest prices per watt for solar photovoltaic panels 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 cheapest panels dollar per watt that we can find on the internet and through direct research. We also include listings of products our readers submit to us through or Contact Us form or in the comments. Representatives of the different vendors are welcome to submit info about their products too. Very differently from other “cheapest solar panels lists” out there we will not charge you for that and we will not tell you the list is already full – yep, this is what some publishers of lowest prices in solar have told some of the vendors of realistically the cheapest panels in certain sizes.

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.

With us having to research so much information about solar and other renewable energy we came across an enormous number of articles in which no respect is given to the units of measure in which electric power and energy are being measured. In actual fact when the correct units of measure are not used the statements do not make any sense.

What do we mean? Much too often watt hour (Wh) and the derivatives kilowatts hour (kWh) and megawatts hour (MWh) – as a measure of produced energy – are used wrongly instead of watt (W) or it’s derivatives kilowatt (kW) and megawatt (MW) and the other way around.

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? Do you want to go completely off-grid and power the whole house by solar power? Either way, you’ll need to know how much energy your home is consuming per month on average.

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.
