Cec Rating Of Solar Panels

The common tier 1 rating was developed by bloomberg new energy finance corporation to rate solar panel manufacturer s in terms of financial stability.

Cec rating of solar panels. The tier 1 rating can be somewhat misleading as it does not guarantee and panel is free from defects or will perform over the life of the system. Wind because solar panels are going to experience some amount of wind being outside of course and the rating standardizes against a slightly lower temperature. The lists helped ensure the solar equipment met minimum safety and performance standards. Ptc dc ratings are published by the california energy commission cec if you need to go find them.

If you are thinking that means not all panels are the same you are correct. It does not mean a panel offers the highest performance or quality. As the panel heats up as they all do in the real world its output goes down. Although ptc ratings offer a realistic view of photovoltaic output they don t indicate exact energy production.

Low med power rating w listed residential 60 cell panels only. The jinko solar jkm260p 60 watts polycrystalline module has a ptc rating of 238 2 watts and an stc rating of 260 watts. What is a tier 1 solar panel. As you can tell by the name this is also rated in terms of direct current.

The cec developed the solar equipment lists under senate bill 1 murray chapter 132 statutes of 2006 establishing criteria and standards for solar incentive programs under the california solar initiative such as the new solar home partnership program nshp. Factors that affect solar panel efficiency. The hi mo3 and hi mo4 mono perc range of panels from longi solar use the common 120 split cell format and are becoming one of the more popular high efficiency low cost panels on the market. Generally if no ptc value is listed in the specifications for a photovoltaic panel you can expect it to be about 10 to 15 percent less efficient than the stc rating.

Browse the clean energy council s list of building approved fire tested solar photovoltaic pv modules suitable for installation under the small scale renewable energy scheme sres. The percentage drop off depends largely on the type of solar panel materials used and the manufacturer. The ptc of solar panels with stc rating of 260 watts varies in the gosolarcalifornia table.
