Hence alternative or renewable sources of energy have to be developed to meet future energy requirement.
Principal Solar Institute PV Module Ratings to Evaluate Lifetime Energy Produ...Rick Borry
Are you aware that the energy produced over 25 years by PV modules can differ by as much as 50 percent, even though they have the same power rating? How do you know which module to select for your project? Choosing low-cost modules can give the impression that a PV project is at grid parity, but the ultimate metric for investors and consumers must be the long-term cost of energy production. Even so, developers cannot make the mistake of paying too much for the highest efficiency PV modules. In this webinar we will share our analysis of the PV module characteristics that determine Lifetime Energy Production™ and discuss the how the Principal Solar Institute PV Module Ratings can be used to select optimum solar panels for your project.
In addition to direct cost-benefit analyses, the PSI PV Module ratings have been used by renewable energy investors in their utility scale solar due diligence process, and by Solarize Frederick County as a mechanism to document installers’ choice of solar system components.

Maximizing Power Production for Small Commercial Projectsallearthrenewables
For any project, return on investment is key, but this is especially true for small commercial projects, where getting the most bang for your buck is essential. The key is reframing your thinking: it’s not just about traditional measures of cost like dollar per watt. Thinking about production capacity, and your dollar per kilowatt-hour, will yield a much better picture of how your project will return–and how you can meet your bottom line.
In this webinar, we’ll take you through the key steps for maximizing your power production in small commercial projects, including choosing panels that will give you more power for your money, how to site effectively to ensure you’re capturing as much sunlight as possible throughout the day, and thinking beyond fixed-mount systems to systems that follow the sun to increase your production by up to 40%.

Editor's Notes
Recorded sun hour data for particular locations is used to help approximate the energy produced by a module, as it is the energy from the sun that is converted to energy from the solar module. The amount of Sun Hours for one particular location differs from day to day. There are multiple Sun Hour data sources that slightly differ from one another. The U.S. Department of Energy and NASA have recorded this data for over 30 years and have calculated average daily sun hour data for most locations, which helps predict approximate yearly energy output for that location. This recorded data shows an approximate daily Sun Hour average of 6.5 hours throughout the year for the Southern Nevada location used in this example. The Sun Hours during the summer season average approximately 7.25 hours per day and the Sun Hours during the winter season average approximately 5.75 hours per day.10 These seasonal averages result in an average of approximately 6.5 Sun Hours per day (7.25 + 5.75 / 2 = 6.5). In order to estimate the yearly energy production of a solar module, one simply multiplies the estimated module energy output (from one sun hour exposure-1000W/m2 over one hour), 71 Watt hours AC in this case, by the amount of Sun Hours for the particular location, 6.5. This results in approximately 461 Watt hours AC per day or .461 kWh AC per day. When estimating yearly energy production, the estimated daily energy production, .461 kWh AC, is multiplied by the total number of days in the year, 365.This results in approximately 168 kWh AC energy production. One 100 Watt DC module can be reasonably expected to produce an average of approximately 168 kilowatt hours AC of energy per year under the specified conditions in this example.11 Sun Hours (Southern Nevada ~6.5 avg. daily sun hours); 461-Watt hours AC per day (71 Watt hours AC x 6.5); 168 kWh/year (.461 kWh/day x 365 days)
6 こちらは京セラの一番の特徴である Reactive Ion Etching の紹介です。 一般的には Chemical Etching という手法でセルの表面に低反射加工を施しますが、 京セラの場合、特殊なテクスチャーパターンを施すことにより、皆様ご存知の濃紺セルを製造しております。 右下図にあります、 RIE によるピラミッド型の特殊テクスチャーは京セラの特許となっており、 Chemical Etching テクスチャーとの差は左下の反射率比較グラフをご覧頂ければ一目瞭然かと思います。 この低反射セルが京セラの高効率製品を生み出す要となっております。 次、お願いします。 This figure shows the spectral reflectance of RIE and other textured surface without anti-reflection coating. Blue line is RIE texture, and this figure shows a SEM image of its surface structure. Red line is photolithografically defined wet etching, and this figure shows a SEM image of its surface structure . Light blue line is CZ texture. We can see that the surface reflectance by RIE is very low as compared with the previous structure by photolithografically defined wet etching. Moreover, RIE texture has lower reflectance as compared with CZ texture.
This shows an application for Football stadium of 1.35MW.

Next, we have to have a way to speak about how the array is oriented to the roof. These terms get tossed around quite a bit, but in general, we talk about the run of the rails. North to South means rails run peak to gutter, and we call this High Profile. East to West means the rails run from eave to eave, also known as Low Profile. THIS IS NOT NECESSARILY REFERRING TO TILTED RACKS.
