So let me see if I have this straight:
• Power costs too much.
• In places where there is lots of sun, people look to solar energy to supplant some of that need.
• But solar panels are very expensive, probably too expensive to ever recoup the cost directly, so the government subsidizes some of the cost. Energy companies also allow some people to connect their panels to the grid, reducing the cost of the electricity that the power company provides.
• That makes solar panels more attractive to buy, and the hope is that the more people adopt the technology the better and less expensive it will become.
• But the power companies aren't prepared for this influx of backfeeding solar customers, and can't adequately provide the equipment necessary to keep the grid running the way it should. So they're telling customers that they can't feed their solar panel energy back into the grid anymore, causing people to complain.
Maybe it's a money grab from the power company, but if it is, it's not a very aggressive one. These people can still use their solar panels to power their own home. Their power bill will still be a slight fraction of what it would be without the panels, they just can't get a negative bill or get it down to as close to nothing as they thought.
