Solar panel with integral battery

solar-battery-lithium-oxygen-diagram-640x319Is it a solar panel with integrated battery, or a battery with an integrated solar panel?  No matter which way you look at it, this new technology being developed at Ohio State is pretty cool.  This solar panel has a layer inside that acts as an energy storage medium.  No separate charge controllers like an external battery would require.  It’s just a solar panel that can continue to supply power once the sun goes down.  Since it’s still in the research stage there’s no word on capacity and those details, but it’s a really neat idea that I hope takes off.  Read more at  ExtremeTech.

Old Energy vs Solar

The fight has begun.  Solar and ‘old energy’ are increasingly butting heads, as the old business model breaks in the face of new distributed solar generation.  Old energy is fighting back with the help of governments reducing incentives for distributed solar installations and even increasing fees for grid-tied systems.  It seems to be slowing down solar adaption in areas, but I think this is just a temporary blip…once energy storage drops in price, people will have a viable solution for going entirely off-grid, and then Old Energy will be faced with the same infrastructure costs, yet with fewer customers to spread that cost over.  The inevitable collapse of Old Energy will be fascinating to observe…I can’t wait!  Read more at  Business Insider.

Solar City to Make Battery Backup Standard

Cool news…using batteries from the gigafactory Tesla is building outside of Reno, Solar City will be including battery backup systems in 100% of the rooftop solar systems they install within 5-10 years.  This is significant partly because it helps illustrate the rapidly decreasing costs of both solar panels and battery backup systems, but also because it is likely to have a major impact on our current energy production and distribution systems…the old grid will become obsolete eventually, but the transition won’t be easy for the larger energy companies.  Read more at

Plug and play solar energy storage system for the home

Bosch-BPT-S5-Hybrid3Bosch is selling a near plug and play energy storage system for home use, the BPT-S 5 Hybrid, a refrigerator-sized cabinet that houses a large battery, charge controller and inverter, to simplify integration with a house’s existing solar and grid lines.  Installation is estimated at a mere two hours!  It’ll charge up when your solar panels are producing excess energy, and discharge that into your house as needed at night.  Unfortunately…it’s only available in Germany at this point. 🙁

Powering the World with Solar

AreaRequired1000Solar panels take space, but just how much land area would need to be covered with solar panels to provide 100% of this planet’s power needs (including transportation)?  The answer is pretty surprising, as the image here shows (click on it for a larger version).  It helps show just how much energy the sun is sending our way, and what a small percentage of that is actually required to power our civilization.

There’s still a matter of energy storage with solar panels, but I wonder, if long range transmission efficiency could be boosted to the point where we have a global power grid?  The sun is always shining on about half the planet…if that power could be transmitted to the dark side of the planet, there would be no need to store electricity.  Nikola Tesla suggested that just such a system could be possible.  The drawbacks are obvious though…it would be difficult or even impossible to employ Tesla’s system in a way that would allow companies to control who uses that energy.  The business model falls apart, sadly, and we live in a world controlled by business and profit.
