Benefits of Buying Vs Leasing Solar Panels

Benefits of Buying Vs Leasing Solar Panels 479 359 Sunlux

When a customer takes the decision of getting a solar system, the tough question is between buying or leasing to own the Solar Panels. If you buy it, the system is yours either if you pay it with cash, or a Solar Loan. If you choose to take a Solar Leasing Programs, the system is owned and maintained by a third party company. Each option impacts directly to the cost, maintenance, terms, savings/returns and financial offsets on your solar panel system agreement.

In the State ofCalifornia the 70% of the residential Solar Systems were funded by an external party, through a Leasing solar panels PPA, Or Solar Service Agreement. The other 30% were either purchases with cash or financing. With this information the big question for people interested in going solar and doing their research before they get the system that fits for their needs would be: Why are the majority of the solar projects funded through a Solar Lease? Because my neighbors are going solar with a lease, should this be the best for me?

We review the benefits of leasing vs purchasing your solar system:

Benefits of Leasing Solar Panels for your house

Save Money right away. You will save about 15-40% of the current utility bill price, depending on the size of your bill. The higher your bill, the more you will save.

No Upfront Cost. You are not required to put money down for installations. Solar Leasing companies pays for everything, from design, engineering, permits, equipment & installation. You only make your lease payment every month once your system is turned on, instead of making the payment to your utility company.

Free Maintenance. If something happens to your system, it’s the leasing company who will fix it. Once again you save as the system is insured by the leasing company.

The system is guaranteed to produce a minimum level of power each year. If the system produces more, it’s totally free for you. If its produces less the leasing company will pay the difference.

Benefits of Buying a Solar Panel System

Cash is always king. Cash purchases give the highest return on your investment. When you purchase, you own the equipment and all the power it produces with little to no operation costs.

Federal Tax Credits. If there are any incentives available such as tax credits or rebates, you can apply for them which reduces your net cost for the equipment. Right now, there is a 30% tax credit from the IRS if you purchase a solar system for your home. You must owe a dollar in federal tax to get a dollar in credit, but it is available if you have a tax appetite.

Increase Home Value. Purchasing a solar system adds value to your home and increases the value of any future sale of your home. A study was made by the Berkeley National Laboratory that gives credibility to this claim.

It does not matter which choice you make when going solar: cash, financed, or lease. All will give you the same power for a lot less money. That’s why people are excited about replacing the utility with solar. The added benefit of getting your power from the sun verses using the carbon rich forms of fossilized fuel is even greater for our planet. You won’t know if leasing solar panels worth it, until you shop around for a solar power lease or a solar financing program.

Solar Roofs vs. Solar Panels – Price Fight!

Solar Roofs vs. Solar Panels – Price Fight! 630 420 Sunlux

The world witnessed the “Evolution of Roofing” late last month, when Tesla CEO, Elon Musk, took the stage at Universal Studios in Los Angeles to unveil the latest concept innovations from SolarCity & Tesla Motors—Solar Roofs, Powerwall 2.0 & PowerPack 2.

While the later two are products worth mentioning and delving deeper into them, this post will primarily focus in what many are still talking about today—Solar Roofs!

Solar Roofs—its cost, feasibility and is it worth it?

Details in regards to cost of the different solar roof shingle options were not disclose during the announcement. However, Consumer Reports Magazine, got themselves to work and made an analysis of it’s own with some interesting calculations.

Based on a 3,000 square foot home, upgrading to a solar roof will cost around $100,000. A staggering figure if you ask me, but based on it’s highly durable tempered glass composition and it’s aesthetically pleasing looks, the question remains the same, is it worth it? And how does it fare vs. conventional solar panels?

Using sources from the Slate Roofing Contractors Association, the Roofing Institute and the Remodeling 2016 Cost. vs. Value Report, here are some costs based on the same size home (3,000 sq. ft) for 3 different kinds of roofing material.

Roofing Material – Cost
1) Clay Tile – $16,000
2) Asphalt – $20,000
3) Slate – $45,000

 

Time for a Price Fight!

Let’s entertain the idea that Solar Roofs are now available and a homeowner is looking at re-doing his/her roof and going solar as well.

Estimating an average utility bill of $2,000 per year ($166/mo.) and considering the current national electric rate increase of 4.7%, according to the U.S. Energy Information Administration, this homeowner is looking at paying $78,890 in the next 25 years should they decide to stay with the utility and not going solar, so all things considered there are three possible outcomes:

1) Do nothing and just re-roof:
– Clay tile: $16,000 + $78,890 = $94,890
– Asphalt: $20,000 + $78,690 = $98,690
– Slate: $45,000 + $78,690 = $123,690

2) Re-roof and install conventional solar panels to offset entire electric bill = $14,000 after tax credits ($20,000 actual system cost)
– Clay tile: $16,000 + $14,000 = $30,000
– Asphalt: $20,000 + $14,000 = $34,000
– Slate: $45,000 + $14,000 = $59,000

3) – Re-roof with a solar roof: $100,000 – 30% Tax Credit = $70,000

Looking at these numbers it seems like option 1 is out of the equation.

If you need a new roof, why not take advantage of properly designing and mounting a system that will maximize the production from your rooftop? Why wait and risk having to deal with roof penetrations and broken tiles that could potentially void the warranty of your roof?

Going back to our cost comparison, it’s really up to 2) solar panels vs 3) solar roof.

Option 2 presents the most immediate return on investment, with almost $40,000 in savings within the 25-year comparison vs. the solar roof alternative. But if Solar Roofs are as durable as they originally claim to be and could last way beyond the 50-year mark, then a key deciding factor of which alternative is best relies in the degradation rate at which the solar cells lose it’s efficiency to produce power.

A top tier-1 panel with high quality solar cells (19% or higher efficiency rate) will lose
0.5%-0.7% of it’s annual power generation. Which means that after 25 years the yield in energy production will decrease 12.5%-17.5%. It may seem like a lot but in reality it’s easy to circumvent around this issue. Simply swapping a few panels for newer and more efficient ones will bring your production back to 100%.

 

In regards to solar roof cells, since not much has been said in terms of efficiency rate and degradation, we will have to wait for new announcements and draw better conclusions.
But for the time being, conventional solar panels are a very safe and cost effective alternative to cut down electric costs for good. While I cannot deny the cool aspect and the pretty looks of the new solar roofs, initial costs seems prohibitable for most. Perhaps the trend will be similar as to the 2011 Tesla Roadster, market to the affluent and generate investments to fund future products we can all enjoy.

For now, let’s give it up for the defending champion and still brightest star in the horizon of clean renewable power—our favorite—The “Not So Old” Solar Panel!
