Cec Rating Of Solar Panels

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.

Cec rating of solar panels.

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. The jinko solar jkm260p 60 watts polycrystalline module has a ptc rating of 238 2 watts and an stc rating of 260 watts. 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. It does not mean a panel offers the highest performance or quality.

What is a tier 1 solar panel. 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. As you can tell by the name this is also rated in terms of direct current. 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 lists helped ensure the solar equipment met minimum safety and performance standards. Factors that affect solar panel efficiency. The ptc of solar panels with stc rating of 260 watts varies in the gosolarcalifornia table. See the bottom of this page for the approved module list for the victorian solar homes program.

If you are thinking that means not all panels are the same you are correct. Low med power rating w listed residential 60 cell panels only. As the panel heats up as they all do in the real world its output goes down. In 2019 small scale solar systems up to 100 kw was responsible for 22 3 per cent of australia s clean energy generation and produced 5 3 per cent of the country s total electricity.

Ptc dc ratings are published by the california energy commission cec if you need to go find them. Most non sunpower panels drop 8 10 and the cec data shows panels that drop as much as 16 5 under ptc testing or to put it another way the panel s ptc rating is 83 5 of its stc rating. The percentage drop off depends largely on the type of solar panel materials used and the manufacturer.
