Tesla Powerwall

Tesla Powerwall: Is it Worth the Investment?

Tesla Powerwall

Tesla Powerwall coupled with solar panels will enable your house to go fully off grid and completely operate on your own energy or utilize a lot less energy from the grid. During the day, the panels will capture electricity from the sun then convert it to energy. Your house will operate off that energy and the excessive energy that isn’t being used is stored in the solar storage system. When the sun sets, your house still will be running off of green, clean solar energy.

Solar Battery Benefits

The most notorious Tesla Powerwall benefit includes producing all your electricity without having to use energy from the energy company. Solar panels oftentimes produce more electricity than a house will use during specific times of the day. With a Powerwall, it’s possible to store this energy for later usage, rather than letting it be wasted.

More importantly, energy providers frequently increase their prices at specific points of the year and the price of energy is consistently increasing. With the Powerwall it’s possible to avoid those peak charges and rates. Even when the solar panels aren’t generating energy your house still will operate on stored energy from the Tesla Powerwall.

The most enticing and final benefit of the Powerwall includes protecting your property when disaster strikes. When your community is struck with hurricanes or winter storms and is out of power, the Tesla Powerwall gives you the capability of powering your residence’s essential electronics with its stored energy.

Why Should You Get the Tesla Powerwall?

If you want to be energy independent, this is what you need. With the combination of your solar panels and Powerwall solar batteries, your house will be pulling much less electricity from the grid than ever before. Fewer fossil fuels will need to be utilized to produce that power, which means less pollution. So, the Tesla Powerwall helps keep the environment green while giving you the benefit of reducing your monthly energy expenses. Contact our team today to learn more!

Solar Panel System: What Size do you Need?

Solar Panel System

You made the decision to switch to clean, green, solar power, and are considering installing a solar panel system. There are some questions you can ask which helps you determine what you would like out of your solar system.

Do you want to lower your electric bill or go off grid?

If you really want to reduce your energy bill, the quantity of solar panels is determined by precisely how much you wish to reduce it by. If you simply want half of your energy usage to be lowered, the solar panel system likely will be smaller. If you wish to cover all of your energy needs, you probably will require a larger solar system in order for it to capture all of the solar power your house needs. Also, you might want to think about buying a solar energy battery that stores all excessive energy the panels will deliver. It’ll permit your house to operate on renewable energy even during the night.

How much energy are you consuming?

If your electric use is fairly low even without panels, it might mean the size of the panel system does not have to be that big. If your panels generate more energy than your house uses on a routine basis, you probably also would want to look at either net metering, or the installation of a solar battery in order for excess energy not to disappear.

How many kilowatt-hours can your panels generate?

The answer to that varies- that is because, like vehicles, solar panels are available in different brands and generate different electricity levels. For instance, a bifacial solar panel that generates electricity from both sides- naturally will produce more energy than single-sided solar panels.

What size system should you get?

The answer to that varies from one house to another, and depends mostly on the aforementioned factors above. If you wish to cover all of your energy needs, you probably will require a bigger solar panel system, meaning of course, more panels. But, if there’s limited space on the roof you might instead utilize higher efficiency panels. It’d mean fewer panels, but more production rates.

Farmer’s Go Solar

An increasing number of agricultural businesses and farms are considering solar as a means to power their day-to-day operations. Thanks partially to the SETO (Solar Energy Technologies Office’s) investments, the price of implementing solar has declined, allowing more installations around the country. Consider the following insight to assist you in determining if this option could be a good fit for you and your farm.

Advantages of co-locating solar & crop production

There are various advantages of co-locating solar & crop production for farmers and solar energy developers.

Advantages to solar developers include:

● Decreased installation expenses – The usage of already tilled land might prevent the necessity for costly grading that is often required for panel installation.
● Decreased upfront risk – Geotechnical risks may boost the price of solar installation because of increased testing requirements. Previously tilled land was marked as the “least risk option” within a sequence of surveys with solar installers.
● Decreased legal risk – In utilizing previously disturbed agricultural land, solar installers may decrease the risk of upfront litigation within the environmental assessment process.
● Possibly increase PV performance – Vegetation beneth modules may increase solar performance and contribute to lower soil temperatures.

Advantages to agricultural land managers include:

● Marketing opportunity to sustainability-mindful audience
● Decreased electricity expenses
● Revenue stream diversification
● Increased capability of installing shade- resistant, high-value crops for brand-new markets
● Capability of maintaining crop production within solar generation
● Permit nutrient and land recharge of degraded agricultural lands.
● Possibility for water usage reduction
● Possibility to prolong growing seasons

Will solar modules dry out and heat up crops or vegetation under these modules?

Solar modules actually will cool vegetation and crops situated below them during the daytime since they offer shading. They have the ability to keep plants warmer in the evening. Research has proven that those temperature variances cancel out and that means day-to-day crop temperatures were similar underneath modules, as compared with full sun crops and there wasn’t any impact on rates of crop growth. Modules may give farmers the capability of growing shade-tolerant crops and diversify crop selection, while simultaneously prolonging growing seasons and decreasing water requirements. A study discovered that shading from solar modules generated lettuce crop weight that was equal to or greater than lettuce that was grown in full sun.

An Increasing Amount of People Are Going Solar Each Year

In the early 2000’s, using solar power was often seen as something only millionaires were able to do. In less than two decades, that has completely changed. In the year 2000, the cost per watt for solar panels was about $10. These days, it’s reduced to $2 to $3. Solar panel efficiency has also increased. In 2012, the greatest efficiency was a little over 17 percent. Five years later in 2017, researchers created a prototype cell which could reach a little over 44 percent efficiency. The intrigue of clean energy such as solar, has led to many local governments, states, and even electricity providers providing financial incentives designed to help more homeowners and business owners invest in solar systems.

industrial solar panels

This increasing trend of folks using solar is having a significant effect on the general electrical production for the United States, as well. Renewable energy, in 2010,  accounted for fewer than 5 percent of the electrical production for the U.S. Nowadays, less than a decade later, it is nearly 15 percent. Plus, utility-scale generation alone is predicted to increase by an additional 17 percent in 2020. Most utility providers who traditionally utilized fossil fuels are now changing over to renewable, clean energy due to the sizable financial savings they’ll bring. Renewable industries such as the solar sector aren’t just booming in the United States. One Bloomberg report claims that by 2050, it is predicted that 50 percent of electricity produced worldwide will come from renewable sources like solar.

It is estimated that the United States will be producing its share of that 50 percent. Currently, 37 states possess renewable portfolio goals or standards for its electricity providers to meet. Thirty-eight states possess net metering, or likewise programs. And it is expected that by the year 2025, state standards are going to support 103GW of renewable energy. By going solar, owners of homes will have the ability to save cash and reduce their utility bill, instead of worrying about increasing electricity rates because of the rising price of fossil fuels.

The Twenty Six Percent Federal Solar Tax Credit

Technological advancements and rapidly growing interest are giving way to solar panels that are more efficient and less expensive. They are an excellent investment, whether you need them for your business, or your home. However, like with any investment, you want to ensure you are receiving the perfect deal for the perfect price. If you are searching for an incentive to try solar, search no further than the twenty six percent Federal Solar Investment Tax Credit.

ground mounted solar panels

This credit, also referred to as the Federal Solar Tax Credit, or ITC, is an incentive that is available to everyone. Whether you are a homeowner, operate a small business, or operate a large corporation, it is possible to take advantage of the incentive. Here’s how it works:

As you invest in solar panels, it’s possible to utilize the Federal Solar Tax Credit to receive 26 percent of the overall expense of the system back in tax credits. This means that more than 1/4 of the price is decreased from the beginning. Plus, if you do not use all of your tax credits in the first year, do not be concerned- they will simply roll directly on over to the next.

Therefore, if you invested in a $20,000 solar panel system, which includes installation, you would receive $5,200 back in tax credits. It would decrease the price of your solar panels to $14,800. Plus, with other potential local and state incentives, you could further decrease the price of your system.

The 26% Federal Solar Tax Credit is an excellent method of getting solar panels for an outstanding cost. But, if you want to take advantage of that incentive and change to solar, you will need to act rapidly. The twenty six percent credit is only available until the end of 2020. Beginning Jan. 1, 2021, the credit will decrease to twenty two percent. Plus, in 2022, it will be fully unavailable for homes.

Could Solar Panels Soon Generate Power at Night?

solar panel roof

As advantageous as existing solar panel technology has been in our search to switch over to renewable energy, historically, these types of panels cannot generate electricity in the evening. New studies now suggest it might be possible to make panels capable of working around the clock.

Below optimum conditions, in the evening, these uniquely made photovoltaic cells might generate 1/4 of the energy they generate in the daytime.

Integration of thermoradiative cells (devices which produce energy because of radiative cooling, in which heat or infrared radiation exits the cell and generates a small quantity of energy within the process) would be needed to accomplish this.

Such cells already are being tested in fields like manufacturing, where they’re utilized to convert waste heat, like the high temperatures produced by an engine.

In the instance of a night-time panel, pointing this type of a cell at the cool night sky is one method of harnessing this process.

According to computer and electrical engineer Jeremy Munday, from the University of California, he was thinking, what if we took one of those devices and placed it inside a warm area then pointed it at the sky?

To accomplish this effect using infrared radiation, it would require various types of materials, similar to standard solar panels, which usually focus on visible light.

Step two includes figuring out what mixture of electronics and materials may generate an efficient panel that may utilize the night space and sky as a heat sink. The underlying math checks out.

Munday adds that a standard solar cell produces power by absorbing sunlight, causing a voltage to appear across the device, as well as for current to flow. In those new devices, light, instead, gets emitted and the voltage and current run in the opposite direction, yet you still produce power.

Under ideal conditions, solar farms might generate as much as 50 watts of power/ square meter, according to the scientists’ calculations – increasing energy generation by around 12% overall in arid, open environments in which many solar farms already are based.

It is a concept that several groups are analyzing. In 2019 we saw an experimental system, established by Stanford University researchers, which additionally utilized the heat imbalance between the night sky and Earth to produce electricity from infrared radiation.

While there is still a long way to go to correctly scale up the technology so that it is useful – currently Munday and his co-workers only have prototypes in development – it’s potentially a fairly inexpensive method of keeping solar cells working 24 hours per day.

The researchers concluded in their published paper that deep space provides an interesting low-temperature thermal sink with the possibility of helping to offer electrical power at day and night through the use of materials science, optics, and photonics.
