Are rooftop photovoltaic panels a waste of money

Is rooftop solar worth it?

Remember that rooftop solar is maybe three to four times as expensive as utility-scale solar and the same trends tend to hold for storage and other resources like that. Then in other locations, we’re actually undervaluing the potential value of distributed energy resources.

Can rooftop solar drive up the cost of distribution systems?

The Future of Solar study did a lot of modeling and simulation and showed that, if you’re not careful, rooftop solar can drive up the cost of distribution systems. There’s also some evidence from other types of what we call distributed energy resources.

How does rooftop solar affect income?

We saw for the bottom 20% of incomes as high as 80% increases in their annual expenditures on electricity as rooftop solar got some pretty substantial penetrations. These are some of the effects that people are really concerned about and some of the problems associated with these rates.

What is New York doing about rooftop solar?

New York has a really concerted effort right now, their Reforming the Energy Vision regulatory proceeding. They’re trying to move from a world where they’re paying rooftop solar adopters based on simply the average cost of the system to a system where they’re actually paying rooftop solar systems for the value that they create.

Could scrap solar panels be cheaper?

New, more efficient designs evolve at regular intervals, meaning it can prove cheaper to replace solar panels that are only 10 or 15 years old with updated versions. If current growth trends are sustained, Ms Collier says, the volume of scrap solar panels could be huge.

Do solar panels go to landfill?

Unfortunately there’s a catch. The replacement rate of solar panels is faster than expected and given the current very high recycling costs, there’s a real danger that all used panels will go straight to landfill (along with equally hard-to-recycle wind turbines).
