Will Solar Energy Be the Cheapest Option? Tue, 05 Nov 2013 17:19:05 +0000 Continue reading ]]> Douglas Hutchings, a tech entrepreneur here in Northwest Arkansas, has recently received half a million dollars in grant money from the Department of Energy for his work on one simple effort: making the materials for solar energy installations cheaper.  Hutchings was quoted as saying that the new technology they’re working on now will make solar energy the cheapest source of electricity available.

Currently, a good solar array can be fairly pricey. The savings on energy can quickly pay back the cost of the installation and then some, but there is an initial investment that can cause some people to hesitate.

Will a solar installation cost less in the future? Probably so. It costs much less now to install solar heating than it did in the 20th century. Most technology does become more efficient and less costly over time.

Should you wait to switch to solar energy in case the price goes down? That’s actually the wrong question. The right question would be: can you wait to use electricity until the price of solar goes down? If not, then waiting for the price of solar to fall means you will be spending more than you need to until that happy day arrives.

Call us now to find out what a switch to renewable energy will cost you. Then you can ask yourself one more question: do I want to make a difference now or later? Switching to renewable energy helps your home or business finances, but it also helps the earth. Why wait?

A New Business Model for Solar Energy? Fri, 12 Jul 2013 17:10:20 +0000 Continue reading ]]> Former U.S. Secretary of Energy Steven Chu would like to see a change in the way solar power is installed  in U.S. homes — not in the technical procedure, but in the business model.

No, homeowners and business owners pay to have renewable energy projects completed on their property. Some of these projects are grid tied — that is, they’re connected with the local electric grid in ways that allow the owner to use electricity from the power company when they choose to or need to, and to sell excess energy production back to the company for credits on their electric bill.

Chu proposes that the power companies should install solar panels (PV modules) and backup batteries free of charge. The owners of the buildings are allowing the power companies to use a small part of their property — say, a corner of their roof — in exchange for the solar power. This gives the power companies a new source for power… potentially millions of new sources.

Consumers will continue to pay for their electricity in the usual way. Costs might be lower, but even if the costs remain the same, consumers will benefit by having the battery backup in place in case of a power outage.

We’d all also benefit by having more of our energy come from renewable sources.

It’s an interesting idea. In the meantime, you have the choice of benefiting immediately from a grid-tied system. Contact us to set the process in motion.

Music Powered by the Sun Thu, 06 Jun 2013 00:15:08 +0000 Continue reading ]]> The Block Street Block Party was a day of sun and fun in downtown Fayetteville, Arkansas. It was also a day of music, on multiple sound stages including this one, where the Fayetteville Roots Festival held sway.

This one was special, as you can see, because the amps were powered by solar energy, courtesy of Rocky Grove Sun Company.

It was a great day to get out and see people, and we hope it was a good reminder that solar power is… well, powerful.

Solar energy has been used for millennia to bake bread, heat water, and grow food. Now we have the technology to harvest this energy and use it as electricity to power anything which uses electricity.

This may seem very obvious to regular users of renewable energy, but we saw some amazed expressions on the faces of people who realized we were using solar energy to amplify music.

That’s why we spend so much time in education.

Check Out Our Sunny New Interactive Map Thu, 06 Jun 2013 01:13:53 +0000 Continue reading ]]> Did you notice the snazzy new interactive map on our homepage? This shows some of the installations we’ve done recently.

The interactive part is that you can move the map around to see more locations, and click on the sun icons to see photos of the solar arrays.

Note the shadow being cast by the bright sunshine at!

Beaver Lake Sun, 26 May 2013 00:59:56 +0000 Continue reading ]]> A beautiful solar array in a beautiful setting overlooking Beaver Lake.

Some people hesitate to consider solar energy for their homes or businesses for fear that the aesthetic value of their building will be lessened.

In fact, a solar array can be very attractive.

John Brown University Gets Solar Power Thu, 16 May 2013 00:39:09 +0000 Continue reading ]]> First of three new solar arrays at John Brown University nears completion. Custom fabricated steel and aluminum racking system attaches modules to existing windscreen. Micro inverters are installed behind each module and produce 208VAC to match the three phase utility service.

What’s more efficient: photosynthesis or photovoltaic cells? Wed, 11 May 2011 16:39:37 +0000 Continue reading ]]> You might be surprised to learn that PV cells beat plants in their efficiency at turning sunlight into energy.

Scientific American reported that photosynthesis turns about 3% of the sunlight a plant receives into energy, while a solar panel harvests about 10% of the energy it receives.

Let this tech triumph help keep your home comfortable and your cooling and heating bills low.

What’s a solar pathfinder? Mon, 09 May 2011 21:15:41 +0000 Continue reading ]]> Here it is, the solar pathfinder.

To get the best return on your solar energy investment, you have to have the right size of array, in the right place, with the right orientation. To calculate these things accurately, you need accurate data about the sun and shade patterns at your site.

We use the solar pathfinder, a highly accurate piece of equipment that measures this information precisely. We can use the data with confidence to design your solar power system.

Together with information on your energy usage and the nature of your building and site, the data from the solar pathfinder lets Rocky Grove plan a system for you that will lower your monthly power bills without giving large donations to the power company, see you through inclement weather, and otherwise meet your goals.

Why choose a solar company that says, “Most folks use…” when you can have exactly what you need, based on accurate information?
