Solar Power: Renewable Energy for the 21st Century
**This is on our website, but in an effort to meet more readers – and hopefully, actors for the planet – the general information bears repeating, in that it may help you decide that you too can go Solar!**
Solar photovoltaics provide the electrical energy that we can use to power our appliances ~and our dreams! With manufacturer warranties of up to 25 years, PVs are a long-term reliable investment that buffers us from a volatile energy market. Since most people in America are already connected to the electric grid, a photovoltaic grid intertie system makes a lot of sense. Net metering (Prop. C in Missouri) allows for us to produce energy at our own home and then use that energy, measured in kW hrs, to offset – at the consumer price rate – what we consume from our electric supplier.
In remote locations, or if one wishes to be off-grid, PV solar panels combined with batteries provide us with energy independence and years of off-grid pleasure! Solar electric power is clean, reliable, affordable, safe, long-lasting and requires very little maintenance.
Germany and Japan have been on the solar energy forefront, leading the way by example and showing us that we can significantly decrease overall energy consumption if each house will offset their energy usage with solar power and energy conservation. With the decreasing prices in solar equipment, Federal Tax Credits and electric provider rebates, solar power is a very attractive and earth-friendly option for anyone wanting to reduce their carbon footprint and be green.
Three Types of PV Systems
The three basic types of photovoltaic systems include: grid-intertie, grid-interactive (with battery backup), and totally off-grid. A grid intertie system allows you to make your own solar power, feed any excess back to the utility grid at the consumer rate, basically using the grid as your storage bank; therefore, excess energy accumulated during the day goes back to the grid, to be used at night or on a another day. In most states, including Missouri, the utility company will offset your PV system production dollar for dollar, until you produce more than you use (avoided costs). Net metering can reduce a utility company’s peak load demand.
A grid interactive system, or grid-intertie system with battery back-up, is different, in that when the electric grid goes down, your essential home electric needs, as determined by you, can be satisfied, through the use of batteries as storage banks.
In a system that is completely off-grid, you are not connected to the electric utility company and all electricity needs are supplied with solar panels and batteries. Occasionally, a generator is needed to fully charge the battery bank.
We have lived off-grid and mainly powered by solar energy here at Silver Seed Farms, Leasburg, Missouri for well over a decade (since 1998). We started out with a very small system and have added to it over time. Our system is still small by some standards. We are fairly frugal with our energy usage and have absolutely no phantom load. It has been an enjoyable and satisfying experience to be using the amazing power of the sun.
