SolarCity Lines Up Backup Service Deal For Raising Funds

As a developer of PV site performance analytics & assessment services--pvwizard.com, I'm quite curious how valuable a 'backup service agreement' can be, over investing into resources for production or revenue assurance. One is a passive, or reactive strategy, while the latter is active, with positive impact on enhancing cash flow.

Solar Energy Rallies on New Beijing Subsidies

I'm glad to hear people getting 100%, even 115% production from their PV array after a few years, without human cleaning. Also, the mention of solar array going strong after 40-plus years! I've seen dirt and grime on every solar site i visited. Without effective, or professional cleaning, these arrays suffer at least 5% in degraded output. Solar arrays are not maintenance-free. Every bit of care and oversight will be paid back with enhanced production. They need to watched over time to time.

Clean Tech Accelerator Funds New Ideas for Global Renewable Energy Applications

I applaud the event sponsor's efforts. Innovation is what can help the U.S. a leader in industries, and our per capita productivity. No idea is silly. Why not turn your critical energy into constructive
suggestions? These teams had devoted hundreds of hours and precious dollars to show-off their innovative ideas and work in progress.

BREAKING: ITC Makes Unanimous Decision on Chinese Cell & Modules

There can be different ways of looking at this situation. The American solar industry(and end customers) benefited from Chinese subsidy, from a record gigawatts of added PV installations. Then the retro-active import tariff brings hundreds of millions dollars into the US Treasury. If the ITC finds harm done to U.S. manufacturers, the tariff amount will expand. Some economist should give us an over-all balance sheet accounting, as further trade war continue.

Solyndra Lawsuit: War of the Solar Dead Solyndra

Well, there is a winner, or two--the DOE SunShot program's goal of seeing $1/watt has been accelerated and reached. Also, the American consumers benefited from the Chinese subsidized products, or generally compressed prices of competing solar modules.

Solyndra Sues Suntech Over Claims of Solar Antitrust Conspiracy

Are we seeing a comic distraction tactic? Solyndra would not have survived even without the Chinese PC cells or modules coming to America!

Solyndra Sues Suntech Over Claims of Solar Antitrust Conspiracy

Solyndra had no value proposition. I could not find any demo or reference installation, with production data to validate performance.
Then its modules costed 3 times as much to make! over conventional thin-film modules. No case.

Car Manufacturers Seek a Solar Boost

Joe,
Good thinking. In fact, it makes great sense for solar charging stations to have solar panels as well. These could be producing DC power that charges the car batteries with higher efficiency too.

Four Charts Provide Distributed Solar Lessons from California

This study result should alleviate some of the reluctance utilities have about adopting solar power. Why do we still have a cap on incentive for renewable ?

Rural Island Power: Solar Computer Lab and Long-distance WiFi Installed at Remote School

This is a wonderful example of collaboration goodwill by the instinutions mentioned. By adding batteries and chargers, systems like this can offer longer hours and extended coverage.
