Are Photo voltaic Panels Likely To 300 Watts Shortly?

This is my 2nd movie job interview with John Shaw Project Engineer Bella Energy of out of Louisville Colorado.

SolarDave: Are Photo voltaic Panels Likely To 300 Watts Shortly?

John Shaw: Totally, any manufacturer can do that appropriate now. You should not definitely search at how numerous watts a panel has – instead how numerous watts per sq. foot can be attained. Powering you is a Sanyo 200, if you maximize the foot print of that panel by fifty% it is a 300 watt panel. The reality is what you need to have to be seeking at to evaluate the amount of development of the engineering is how numerous watts per sq. foot.

Rather of contemplating will there ever be a 300 watt panel – surely there will be even upcoming year. To get at the place of your concern is do you ever think we will be ever to accomplish a 300 watt panel in 15 sq. toes?

And indeed, I do. Ideal now typical performance panels are in the ballpark of about 12 watts per sq. foot, it ranges from ten to 13. Typical performance panels Evergreens, Sharps, Kyocera, Shot (?), Suntech etc.

Maintain in intellect this is the residential very affordable panels, NASA functions with panels that are about thirty watts per sq. foot but you are chatting a million bucks a panel.

Then there are substantial performance panels of the kinds we know of are SunPower and Sanyo. And Sunpower and Sanyo are somewhere around 15 watts per sq. foot. The two are very great products and solutions.

Sanyo I believe has a minimal little bit of an edge because they has an amorphous or thin movie rap all-around the silicon cell which permits them to preserve substantial generation in substantial warmth. One particular a lot more purpose and I will tie this in.

The Sanyo’s are delivered with a minus and a furthermore five percent so when you invest in a 200 watt Sanyo panel you will get hypothetically in typical check disorders 75 levels at sea amount you will get 200 watts or up to 210 watts.

All other panels like specifically Sunpower are + or – five%, so you could invest in a 210 watt Sunpower cell and it could truly conduct at 199 watts exactly where you could invest in a 200 watt Sanyo cell it could conduct at 210 watts, but no less than 200 watts.

So that and the actuality the Sanyo’s will out conduct Sunpower apples to apples same azimuth and pitch in substantial warmth because of this amorphous or thin movie rap ten% in substantial warmth peak times peak several hours – we truly feel Sanyo is a far better panel.

But I have to say that Sanyo’s are a lot more high priced than Sunpower. We can’t contact the Sunpower price, we can contact it with typical performance panels – blow it out of the water with typical performance panels. But if you are chatting about substantial performance panels and substantial performance I think Sanyo is a far better panel but the Sunpower is definately a far better price.
