A reported tug of war between JPMorgan Chase & Co. and Goldman Sachs over the U.K.'s Southern Water has left Goldman in the mud.

JPMorgan, teamed up with Australia's Challenger Infrastructure Fund and other funds, grabbed the water and wastewater company from Royal Bank of Scotland for about $2.7 billion.

There were, of course, some solar deals this week as well, with Santa Clara, Calif.-based Innovalight topping the list. The developer of printed solar cells raised $28 million in Series C financing.

But perhaps the most interesting deal was a funding round for the U.K.'s Perpetuum, a company that makes a vibration energy-harvesting generator. Do you strap it to a hyperactive 3 year old for power?

Deals we saw this week:

• Santa Clara, Calif.-based Innovalight, a developer of silicon ink-based printed solar cells, raised $28 million in Series C financing.

Existing investors Apax Partners, ARCH Venture Partners, Harris & Harris Group, Sevin Rosen Funds and Triton Ventures also participated in the financing.
• New York's JPMorgan Chase & Co. led a group that bought the U.K.'s Southern Water from Royal Bank of Scotland for about $2.7 billion. JPMorgan partnered with Australia's Challenger Infrastructure Fund and other funds to buy the water and wastewater services company. JPMorgan reportedly beat out a group of bidders led by Goldman Sachs for the water utility.
