A Solar Energy Efficiency Study Finds There’s No Difference Between the ‘Perfect’ Solar Roof and ‘Not Perfect’ solar panels
The article by David B. Brown, MD, Associate Professor of Biomedical Engineering, Harvard Medical School, Harvard University, and the Harvard School of Public Health, has been widely shared on the Web and blogs since April 4.

Dr. Breda said that the study was a good first step, and that it provided a useful starting point for evaluating solar energy efficiency in the future.
“This study provides an important first step to help the development of future energy efficiency and solar PV technologies,” Dr. Barreda told RenewEconomy.
The study was done on a sample of 1,965 residential solar PV systems.
It measured the efficiency of the solar panels in three different configurations: a solar energy system (1 watt per square meter of solar photovoltaic cells), a solar efficiency (equivalent to a 10% efficiency rating for conventional panels), and a hybrid solar energy (equivalently a 10%-50% efficiency rated solar power system).
The team also examined the performance characteristics of each of the panels in terms of performance and thermal properties.
The researchers determined the efficiency ratings for the three different solar panels to be the following: 1 watt per sq. meter, the standard for efficiency ratings; 1 watt solar PV, equivalent to a 50% efficiency for conventional photovolts; and a 10 watt solar efficiency rating, equivalent the equivalent of a 50%-100% efficiency of conventional photolts.
Dr. Barbeda added that it was not a definitive test, because it does not account for any of the other factors that can affect efficiency and performance, such as the cost of the panel or the solar energy.
In addition, it does take into account the amount of solar power used by the system, and how much of the energy is used to produce the electricity.
He said that in order to test efficiency, the researchers also had to measure the thermal properties of the system in addition to the solar efficiency ratings.
“We didn’t use thermal conductivity, which means the energy that was produced from the panels is absorbed and released into the surrounding environment, and there is a net loss of heat,” Dr Bredas said.
“So this was a measurement of the overall thermal conductance of the systems, and we used thermal conductors like silicon, which has good thermal conductivities.”
Dr. Bledas said that since this study was conducted, more studies have been done on solar panels.
A solar energy solar power plant, designed by Dr Barredas, is seen in Los Angeles, California.
The project is being built by the Los Angeles Solar Energy Systems.
According to the study, the study’s results suggest that for solar power systems, efficiency is not a major issue.
“However, for solar energy systems that use thermal energy, the performance is important and is dependent on the thermal conductances of the photovolaics,” Dr Barbedas said in a statement.
According to Dr. J. R. Schuster, a research scientist at the Harvard-MIT Center for Solar Energy and the Solar Energy Technologies, a significant aspect of the study is the fact that it took into account both the thermal and electrical properties of each solar panel.
Schuster said that a number of research groups are looking into ways to reduce the amount that is wasted and how efficient solar energy is.
He added that the research is being done in collaboration with the American Solar Society and other groups, which he said is a good start.
“The goal of this study is to be able to identify technologies that are more cost-effective for large-scale solar energy installations,” Dr Schuster said.
Dr. Schusters research group is also looking at the use of hybrid systems, which are similar to the traditional hybrid PV systems that have been used in the U.S. for several decades.
For example, the Hybrid Solar Energy System, which uses solar energy and energy storage, was designed in the 1980s to help meet the energy demands of large industrial sites.
It was used in California for the first time last year, and Dr. Schusters group is currently working on another project to use hybrid solar panels on buildings.
As part of that study, Dr. Brreda is also working on a study of the impact of various technologies on efficiency.
When a hybrid system is installed, Dr Barledas stated that the amount spent on the energy system is limited
