Solar Info Session

This coming Wednesday, August 3rd, from 7-8:30 pm we’ll be putting on a solar system information session at Castlemakers. This no-charge presentation will briefly discuss general types of solar systems used in homes, then dive deeper into photovoltaic systems and solar panels. If there’s time, we’ll also talk briefly about how to determine solar potential at your location. If you’d like to read more, here’s a blog post that covers a session we did before.

A Real Solar Gain

Castlemakers is pleased to share the news about our SIA Foundation grant to create a Solar / Photovoltaic Resource Center for the community. The grant will be used to install and demonstrate a working photovoltaic system at our makerspace. The most visible portion of the system will be a solar awning, which has been designed to blend into the streetscape on Franklin Street.

Besides the hands-on working solar/photovoltaic system, which will show makerspace power usage & creation, Castlemakers will add resources and equipment to learn more on solar and photovoltaic technology. Besides the solar awning, we’ll have:
– Projects to demonstrate photovoltaic creation for youth and adults.
– Classes & sessions to help everyone to learn about the technology
– Equipment to help with solar measurement & assessment
– A reference library of books and materials.

There’s still a lot to do before everything’s in place; we’re currently designing , getting approvals, & purchasing equipment. But we’ve already started offering classes and will have projects in the next few months – including building a solar generator. We’re excited to help put a little more ‘green’ into the area by encouraging more solar power!

Solar Energy Class

Presentation on installing & using solar power to reduce your electric bill.

Saturday we had the 2nd of two adult classes this month, the first a week earlier was an updated Photogrammetry class like what we taught in the fall. Great class, Rebecca Kerns did an excellent job where we showed folks about using Agisoft’s Metashape (formerly Photoscan) & 3DFlow’s Zephyr. A few folks hung around afterwards, we did a cellphone video of a model car that was converted into a computer 3D model.

A solar survey tool can determine percentage of direct light during the day & year.

The second class, on installing and using Solar Power, was taught by Ed Kirkpatrick – who had more experience than all of us realized! He offered to talk about his experiences with installing the solar panel system on his house, but it turns out he’s been working with different solar systems for years! Starting with R-values and how they save energy, he then covered some of the passive systems he’s built, including heating rocks/walls and solar water heaters.

Ed discusses recent solar panel cost trends.

But most of the talk was on photovoltaic panels. Ed has a 3000 watt system at home he’s upgrading to 6000 watts this summer. And is involved in ETA‘s solar installer certification program. He not only covered the correct way to survey for and install panels, but also different kinds and cost trends. We even got into batteries and storage systems. The group had lots of questions which were answered, then finished up by going outside and using a Solar Pathfinder to do a solar site survey in front of Castlemakers. Thanks for the great class Ed!!
