The problem

Apartment renters need the landlord’s permission to install anything on their rooftops. This makes installing solar difficult for people who rent. Because most of the world lives in urbanized areas where renting is common, I think this is a problem standing in the way of solar adoption.

An additional speed bump is the complexity of installing solar: regulation around net-metering. Grid-tied systems. Installation permits (even if you do own your property). Getting quotes from different installers. Solar financing. All complex processes inherited from the construction industry which slow down mass private adoption of renewables.

We attempt to bypass both these problems by building a standalone solar power plant on for windowsill, rooftop or garden with off-the-shelf parts, and discuss the pros and cons of this approach to solar.


A possible solution

A windowsill solar system we install ourselves solves both problems at once: Renters don’t need permission from their landlords to place things on their windowsill and rooftops if it’s not altering the building, and it’s a one-click, direct purchase with no regulation as long as it’s not tied to the grid (which this one is designed not to be). Two birds with one stone. This makes the solar buying process more like buying a consumer electronic.

Our mission is to make purchasing solar/storage as easy as purchasing any other consumer electronic, as we believe in a bottom-up approach: once renewable energy does not require a professional it will spread as rapidly as other consumer electronics like satellite dishes and window AC units, etc.

Solar as a modular consumer electronic - like satellite dishes and air conditioning? (Satellite Photo by Paweł Czerwiński | Air Conditioner Photo by Chromatograph)

What if decentralized electric generation could be added room by room to a household (like window A/C units)?

If we look to the car, the smartphone, the window A/C unit — these devices spread like wildfire across the globe because they were off-the-shelf products that required no configuration but great benefits. Identical appliances were churned out at an industrial scale for a global audience. They were “plug n play”. Plug n play solar has been around for a while, but has never taken off (probably because behind-the-meter power is still sketchy and poorly understood). The potential for plug n play solar is huge — it could mean cheap, zero-configuration solar energy spreading to consumers at the pace of the smartphone, the car or air-conditioning.

I'm a healthy mix of prepper and sustainability person. This scratches both itches.

We've mainly been using this in our RV when we're off-grid for a few days... amazingly powerful.
