Happy Tuesday, everyone. Here’s your rundown of solar energy news:

Healthcare giant Kaiser Permanente will install solar panels at 15 of its California facilities, reports the San Francisco Chronicle. San Francisco-based Recurrent Energy will head up the solar installations, which together will represent about 15 megawatts of generation capacity.

In solar industry news, Enphase Energy Inc. — a maker of micro-inverters — has raised $40 million from a number of Silicon Valley investors, according to the San Jose Business Journal.

Kate Galbraith of Green Inc. this morning considers the likelihood that Texas will adopt tougher energy-efficiency standards and strengthen the state’s renewable energy standard as it pertains to non-wind resources, like solar and geothermal. All told, the state could require that 500 megawatts of solar power be brought online in coming years — a small amount relative to Texas’ electricity demand, but a large increase from the seven or so megawatts of solar currently in place.

Today is the last day to register for the Tufts Energy Conference before registration prices go up. The event, which will place April 16-17, looks awesome. I encourage all of you Boston area folks — and those willing to make the trip — to attend.

Finally today, more about solar schools: via MarketWire comes news of the commission of a new 445-kilowatt solar panel array in Winsted, Connecticut. The system — which was installed on a number of rooftops across the Winsted School District — should produce nearly half-a-million kilowatt-hours (kWhs) of clean electricity in its first year of operation, saving the district about $26,000. The project was made possible by a grant from the Connecticut Clean Energy Fund (CCEF).
