In the tiny town of Tenna in Switzerland local residents came together to replace the old and dilapidated ski lift at their local mountain resort. Instead of simply replacing the lift they decided to break some new ground and funded the world’s first solar powered ski lift.

The system produces 90000 kilowatt-hours per year or nearly 3 times the amount of energy needed to run the lift. The modules also are able to track the sun and shed snow when necessary.

So, when is Mt Hood going to follow suit and solarize its lifts?

Low Cost Solutions for Lighting in the Developing World

Here in the US many of us take light for granted. We flip a switch and our incandescent, compact fluorescent, or LED lights up. Much of the world is without this luxury. Children huddle around kerosene lamps at night just to be able to study. Solar energy has the possibility of bringing light to many around the world but the technology is still expensive (but getting cheaper) and their are other hurdles as well (batteries, maintenance, installation). Many researchers and scientists are developing new innovative low cost measures to provide light for rural areas. One such technology that struck me as very innovative is the “solar bottle bulb”. The materials required are a plastic 1 liter bottle, sheet roofing metal, water, and chlorine.

Have a look at this video. Brilliant!

Portland Community Solar RFP

The Portland Bureau of planning and sustainability recently released an RFP (request for proposal) for “Private-Sector Partnerships to Finance Community-Supported Solar Electric Systems on Public Facilities”. In layman’s terms, an RFP to help generate models for community supported solar energy projects on public facilities.

The Problem

Not everyone has the ability to install solar panels on their home. They might be renters instead of homeowners, have a low credit score, have a roof with too much shade or an improper orientation, not have the funds for a residential size system, or live in a condo. There are numerous reasons why solar doesn’t work for everyone even if they are enthusiastic about the technology.

Non profits, schools, and public buildings also struggle to be able to install solar. Even though many of these institutions have ideal rooftops and sites for solar, they lack the tax appetite to make effective use of the available incentives. Without outside grant money, there is little financial incentive for these institutions to install solar panels.

What if there could be a way to connect the community members who want to be a part of a solar project but can’t with the non-profts and schools that need solar the most?

The Solution

Community solar is a way to connect community members, businesses, and non-profits in a collaborative way that benefits all. There are various models that have been used across the country with varying degrees of success. To read more about these different approaches have a look at our past article on community solar programs.

The Portland community solar RFP devised a simple flowchart that helps conceptualize the community driven approach.

At the center of the diagram is a local for profit business with a tax appetite that can benefit from tax incentives. The business initially owns the system and gets a 30% federal tax credit as well as the accelerated depreciation. The business also receives monthly production payments that come from Oregon’s feed-in tariff program. To make the deal economically viable for a business a part of the upfront cost would also need to be provided by community members. In exchange for community financial support, the members can receive either monetary reimbursement or some kind of tangible benefit (a coupon, retail item).

The non-profit/school/public facility is the site host and would be the beneficiary of a reduced energy bill and in the case of a school would have the educational benefits associated with having a solar array.
