As it turns out solar panel efficiency does not follow Moore’s Law.
In one of my first posts I ask the question if I buy a solar panel array now, will it become obsolete in two years like computers do (Moore’s Law).
Looks like SunPower’s previous record of 22% (cell rating) has been shattered with Spectrolab’s 40%.
Jaxsun however pointed out from the previous post that this can be misleading since this is on a cell level and not on a panel level (panels have loss).
Solar panels are not like computers. If you always waited to buy a faster computer, you’d never own one.
Rebates only decrease over time as the gov’t has temporarily provided money to get solar started, not to keep it going.
And every $ you pay in electricity bills is rent money to the electric company. If you install solar panels, then every $ you don’t pay to the electric company goes to pay off the cost of solar. And eventually (when you’ve saved as much money as the solar system cost), then every $ saved is money in your pocket.
Keep up the good work Dave,
