Solar Cars: How You Can Save Thousands on Gas by Going Solar

Filling up your gas tank can be one of the most painful parts of the day.

You work hard for your money, and watching how much of that hard work gets wasted at the pump can be a bit discouraging.  For many of us, gas is a huge expense that can eat up a lot of our money.  If only we could break our addiction to that liquid gold that is gasoline, we could save money we never knew we had.

The good news is, you can break the gasoline addiction.  No, you don’t have to ride a bike, but nowadays, the payoff of owning an electric car is hard to ignore.  The hybrids and full electric cars out there today are becoming more mainstream, and more and more people are waking up to the savings that an electric car can bring.

Let’s break down the savings.

A standard gasoline car gets about 20 miles to the gallon.  Gas, although it does fluctuate a lot, is generally around $4.00 a gallon.  So the cost per mile of driving a standard gasoline car is about 20 cents a mile.

The standard electric car these days gets about 3.5 miles for every kilowatt-hour.  The average kilowatt-hour costs a homeowner about 20 cents per kWh.  So the cost per mile of driving an electric car that your charge at home is about 5.7 cents a mile.

So the saving are obvious there.  By switching to electric, the cost to drive your car literally is cut by almost 75%.  Pretty incredible right?  But think about this:  what if your electricity was costing you less?

By switching to solar energy to power your home, you can cut your power bills by more than half. The average solar installation makes the cost of a kilowatt-hour drop from 20 cents a kWh to 7 cents a kWh.

So how does this translate to savings when it comes to driving?

Solar cars, when powered by a solar powered home, will cost only 2 cents per mile to drive.  With electric cars getting 3.5 miles per kWh, at 7 cents a kWh, solar powered cars save you 90% per mile.

So it’s obvious that solar cars are the cheapest way to get around.  The question remains though as to how expensive these electric cars are compared to their counterparts, and how easy they are to attain.

The new hybrid 2015 Nissan Leaf starts at $29,000.  They are now easily available at any Nissan dealership.  A comparable non-electric car of similar size from Nissan, the 2015 Nissan Sentra, a similar sized hatchback, starts at around $16,500.

So let’s look at how the gas savings compare.  Let’s say you commute 30 miles a day, five days a week.  So you drive 150 miles a week, 600 miles a month, and 7,200 miles a year.

Nissan Sentra: 7,200 Miles X 20 cents a mile = 144,000 cents, or $1,440 for a years’ worth of driving.

Nissan Leaf (without solar powered home): 7,200 Miles X 5.7 cents a mile = 41,040 cents or $410.40 for a year’s worth of driving.

Nissan Leaf (with solar powered home): 7,200 Miles X 2 cents a Mile = 14,400 cents, or $144 for a years’ worth of driving.

So if you’re driving a solar powered car, you could be saving around $1,300 a year on gas.  The savings on gas will make up for the price difference between the Leaf and the Sentra in around 9 years, and after that it’s purely savings.

Setting an example for anyone considering solar powered cars is Stellar Solar’s own VP of Sales and Marketing Michael Powers.  Powers drives his Nissan Leaf to and from work every day, and plugs it in to his solar powered home at night. In a recent interview with the Union Tribune, Michael had this to say about his solar car:  “I drive an electric car that I plug into a solar-powered house so that car runs on sunshine, and to me that’s a great idea.”

How Valuable is a PV Solar System?

We’ve all heard it before.

The benefits of adding a photovoltaic solar system to your home are innumerable, but one that you always hear is that it adds value to your home.

photovoltaic solar system

That should be obvious, as the systems are expensive and save tons of money, but the question of just how much value they add to your home has mostly remained unanswered, up until recently.

 In conjunction with Sandia National Laboratories, researchers at the U.S. Department of Energy’s Lawrence Berkley National Laboratory have recently completed the largest study on the effect of solar photovoltaic systems on home values in history.  Researchers more than doubled the amount of solar homes evaluated from previous studies, looking at around 22,000 home sales, 4,000 of which had PV systems.  In order to open up the scope of the research, researchers also looked at eight states outside of California where solar is not as prevalent.  Considering all these factors, the study is the most extensive of its kind.

The research determined that home buyers will pay about $4 per watt of installed PV, which averages out to about a $15,000 premium per home.  This value is averaged based on information gathered from housing busts, booms, and recoveries, so if projections are accurate, it should remain consistent.

The next step towards achieving this standard of value for PV systems is for realtors to be able to more accurately appraise homes with systems installed.  Hopefully, researchers will continue to improve valuing methods that realtors will adopt, and the value of PV systems will remain consistent and measurable.

2013 and Beyond: Future of Renewable Energy

We’re all watching as San Diego’s local government, San Diego businesses, investors and home owners are making a financial choice to go solar in San Diego. Every indication is that they will continue to do so well into the future. With evidence showing that renewables such photovoltaic solar being the way forward, we look forward to meeting these challenges in the future with our San Diego solar alliance.

But where is the San Diego solar power industry headed, or on a larger scale, where is the renewable energy industry going? According to the new Renewables Global Futures Report 2013 by the global renewable energy policy network REN-21; the future of the renewable energy industry is dependent on ‘finance, risk-return profiles, business models, investment lifetimes and a host of other economic, policy and social factors.’

Okay, this is perhaps a standard bit of insight that is largely applicable to any other industry. Still, it’s worth examining this and other reports to understand what is in store for renewables in 2013 and beyond. Examining the final quarter of 2012, the latest Energy Industries Council Monitor report found that the renewable energy sector grew by 9%. Additionally, there were 295 new projects in the renewable sector worth around $165.3 billion in the latter half of 2012.

Contrasted with the power sector which saw new projects drop by 14%; an even stronger renewable sector picture is painted. Further, investors more than doubled their renewable energy sector investment in 2012, accounting for a third of renewable value last year generated by ever diverse groups of buyers. PwC global power and utilities leader Norbert Schwieters stated that outside investors now account for ‘37% of industry buyer share, attracted by long-term growth and steady-return potential.’

REN-21’s report further found that ‘finance challenge’ is the primary challenge. This can be met with greater external investment and investment models created by local government, services, and utilities. REN-21 also made projections of a massive $500 billion renewable energy investment by 2020. This is all highly encouraging to both the San Diego solar energy scene and the renewable energy industry in general. We’re excited to be a part of it.
