The freedoms we experience in the rural, off-grid setting are immeasurable and priceless.

We’re in full control of our resources and the means by which we utilize them.

But what we sacrifice for freedom and independence while living off-grid is the security, consistency, and reliable structure of on-grid systems.

Would it be possible to have your own mini-grid lighting system that could be taken with you wherever you go?

Biolite, the makers of the ultra-popular Campstove 2, devised the SolarHome 620 for this very purpose.

It’s a complete, solar-powered lighting system that equips any off-grid setting with reliable power and illumination.

This is my review of the Biolite SolarHome 620.

The Biolite SolarHome 620 is a complete solar-powered lighting system with charging capabilities for small devices and a built-in mp3/radio system. Complete with a control panel, lamps, cables, and switches, the SolarHome 620 can provide up to 20 watt-hours of power.

The SolarHome comes with a 6-watt, 11" x 7", all-weather solar panel that remains in a permanent location on the roof of the residence or mobile vehicle. A 21-foot cable connects the solar panel to the control box, where the electrical power is managed.

The control box itself has a built-in light and a backlit LED screen for monitoring the sun intake and battery level. It has the capability of listening to FM radio and playing MP3s.

Additional cables run from the control box to the hanging lamps that can be positioned in various places. Each lamp is controlled by its own on/off switch. One of the lamps comes with a motion sensor.

The Biolite SolarHome 620 works very well as an off-grid lighting system for rural or mobile applications. Whether for a mobile home setup, an off-grid cabin, or a rural home in a developing region, the SolarHome can provide a simple and reliable lighting system and battery.

The daisy-chaining capability allows for freedom in placing the lamps in the most desirable locations.

The lights themselves are fairly bright (100 lumens), and each one, in most cases, is enough to illuminate its own small room.

The solar panel works best under consistent, direct sunlight, so optimal placement of the panel is important. Under hot, direct sun, the battery can fully charge in about 6 hours.

The "620" in the name, SolarHome 620, comes from the 6-watt solar panel and the 20-watt-hour battery bank. In even average sunlight conditions, the SolarHome 620 can be used moderately at night and charged during the day without a break in power.

Why is the Biolite SolarHome Useful?

Energy efficiency is an important topic. But while it may mean one thing to an environmental activist, the self-sufficiency advocate may see it from a different angle.

Those living in rural, off-grid settings aim to live independently and freely, enjoying the beautiful aspects of nature and relying on the land for sustenance. The drawback is that some of the conveniences of being connected to a power grid must be sacrificed. But that doesn't mean that everything must be sacrificed.

What the Biolite SolarHome does is provide a bridge between having the convenience of modern lighting without being connected to the grid. The sun is an abundant energy source that requires no charging, refueling, or connecting to. And by harnessing its power through solar panels, that energy is stored to be used later when the sun sets.

The SolarHome system isn't powerful enough to run all electronic appliances a home in the city would require, but it provides a supplemental energy source. If combined with other energy sources, such as a wind turbine or a solar generator, it may be just enough to provide all the basic electronic needs for a small rural home or cabin.

The key to self-sufficiency is recognizing your needs, limits, and resources and strategizing how to make the best of it. What makes the SolarHomoe useful is that the energy source it relies on, the sun, is unlimited.
