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.

4 Favorite Easy Tips for Winterizing Your Home (Saving Money and the Planet)

If you are serious about changing your carbon footprint or about saving money, then this article is for you.  Rex and I are big believers in energy audits, because you would be surprised to know how much a “regular” house leaks.  However, I like knowing that there are ways that I can personally accomplish something that will save us money and time and is ultimately good for the planet.  I especially like knowing there are easy ways.  I can imagine that I have options, and they seem attainable.

Within this informational slide show by The Daily Green, there are ways to clean out or tweak your current large, energy-consuming appliances and ways to get the most out of what you already have, and many of them for the DIY’er.  There are many important weatherizing improvements listed, such as caulking, sealing, and insulating around windows, and cleaning out or replacing appliance filters.  You should always determine if your improvements are covered by state or federal rebates, tax deductions, or if you qualify for low-income weatherization programs in your area.  You can Google that for your state.  Here in Missouri, we have several.  So in addition, I have a few favorites on this list of weatherization tips.

Okay, now the fun part.  My favorite Top 4 Weatherization Tips:

images Possibly the first thing we do in the fall in Missouri, is to get out our sweaters and jackets.  We really look forward to the autumn change in weather, in part because it generally follows a pretty hot summer, and also because of the beautiful autumn colors.  However, sweaters are not just for the outdoors; a light-weight sweater-type layer (over a sleeveless shirt or t-shirt) works beautifully inside the house to help maintain a comfortable body temperature without having to pay $ for it daily, as you would by turning UP your thermostat.  And it just feels right, like you could be snuggled up with a kitty in your lap, drinking a piping hot cup of tea.  For you die-hard t-shirts-and-flip-flops-in-winter folks – remember, it’s also better for your health to keep your room temperatures lower, and it’s better for the planet.

Another one of my favorite suggestions for winterizing your home is using an energy monitor.  ted-winterize-lgAbsolutely a favorite!  Especially, if you like to read gauges and thermometers, you will get a thrill from monitoring your energy usage.  We have a voltmeter in the house, which tells us how much solar energy we have stored in the batteries.  Also, our inverter tells us how much AC it is creating, which translates into how many watts we are currently using.  It helps you keep your usage in check.  Our batteries get more of a challenge during winter, so a monitor really helps us stay on top of things and adjust our usage.

**A sidebar: .  AC is Alternating Current, that which is grid electricity and DC is Direct Current, which is produced by solar power.  The inverter allows DC to switch into AC to be used in the house with regular electrical appliances.  We use both AC and DC in our off-grid application.  DC appliances tend to be more expensive and less available, but they are more efficient than AC appliances.  It’s a trade-off.  Our inverter is fairly efficient, inverting 93% of incoming DC current to AC, but inverters are different, some more efficient than others. **

This is a super-cool idea!  Get creative with your refrigeration to save energy and money.

air-fridge-winterize-lg (1)  Take advantage of the cold winter air outside to cool a hand-built insulated cabinet attached to your house, through a door or even through a window (which we used to do!).  This blog article says all you need is some wood, insulation and a couple of computer fans (or socks!).  Get detailed with the super-frig. 

And last but not least – my #1 favorite, because it requires some creativity and sewing on my part.  😉  A Draft Snake ~  You can find many different styles to purchase too.

Dodging Drafts:  According to the U. S. Department of Energy, doors and windows can waste 5% to 30% of your energy.  That’s a lot.  As a tribute to what may have started back in the Great Depression, we can see some very artistic modern versions of this tried-and-true method, some with a lot of personality.

These draft snakes can be as subtle as the fabric they are made with,  such as this beauty on the windowsill, buttons-draft-snake-lg or they can be bright and lovely like this patchwork snake.

It’s especially fun when children can get in on the action, maybe even helping to make one.  Or, you may have to make a special snake just for your little one, since it may be moved all about the house, doing a different job – that of companion snake. 🙂

One blog post states:  “In the fight against cold drafts (not to mention pollution and global warming), draft snakes can be real superheroes.”

Enjoy your process of weatherizing your home!  By all means, get an energy audit and save yourself some dough; many states offer rebates for weatherization if it involves an energy audit.  Inspire others, and share your photos and ideas here.  I will be sharing photos of my draft snake soon.

Cheers!
