What will you do when the power goes out?

The electric grid is a wonderful thing. The engineering behind properly balancing electricity generation with electricity load throughout the day is an amazing feat. The achievement of delivering electricity through transmission and distribution lines from large central generation to every neighborhood is incredible. The workers who keep the power on and brave the worst weather to restore power are to be praised. Our grid, though, is vulnerable to weather, imbalances, and other threats. Preparation and planning for power outages can make sure your home’s critical electricity users are sustainably powered from your own solar PV system.

Mountain View Solar is our region’s leader in home battery systems with more than a decade of installing home battery systems for everything from fully off-grid cabins to suburban homes with HOA’s. Our solar consultants and our in-house applications engineer work to custom-size your battery system to power your specific electricity users. While other companies offer a one-size-fits all approach and often only offer one type of system, our professionals work with you to select the specific solar and battery system for your needs.

Our team is now proud to offer the SolarEdge Energy Hub inverter and SolarEdge Energy Bank battery backup system. Manufactured by the world’s leading inverter maker, the Energy Hub + Energy Bank combination offers homeowners scalable resilience. The beauty of the Energy Hub + Energy Bank combination is it creates a mini “micro-grid” for a homeowner as the system also has the capability to recharge the battery via a generator. This built-in redundancy, with the generator acting as a seldom-used, but important back-up to the back-up ensures your home’s critical users will be powered during the darkest days of winter when solar recharging is the least.

The other beauties of the SolarEdge Energy Hub + Energy Bank system are that:

  • it features DC to DC charging for maximum overall efficiency (94.5% round trip efficiency)
  • during times of grid connection, the batteries can charge and electricity can be exported to the grid
  • it can be paired with SolarEdge’s fast electric vehicle charger for car charging when the power is out

Importantly a typical solar photovoltaic system without a battery will not deliver any electricity to your home during a power outage. A battery system with the capability to disconnect your home from the broader electric grid to create a mini micro-grid in your home is necessary in order to have electricity during an outage, even if you have solar panels.

Our team is excited about adding SolarEdge’s Energy Hub + Energy Bank to our battery offerings which include Tesla PowerWall, enPhase enCharge, and Schneider XW with lithium battery systems. Each battery system has its best use case and our team hears your needs to select the best battery to fit your home and your budget.

Speaking of budget, our team offers 100%, $0 down, financing so your entire solar and battery system can be paid through monthly payments. You can sign a contract with us, we permit, procure, and install your system, we work with the utility to get your system turned on, and you don’t pay anything until your monthly payments start after your system is up and running.

Our in-house solar professionals are here to provide your no-cost system design and would love to connect for a friendly conversation. Contact us today and we can get the ball rolling so you are prepared for the next power outage. Click here to request a free estimate: https://mtvsolar.com/site-evaluation/

It’s a Slam Dunk: Solar + Efficiency

Clean energy and efficiency is trending. Homeowners and businesses alike are opting for Energy Star appliances and green energy generation such as solar. The reason changes person to person and company to company. Some have a deep concern for the environment. Others like the idea of self-sustainability. Everyone, though, likes the idea of saving money. And that is exactly what solar energy systems do. They require an initial investment, but the return on that investment will be impressive over the long-term. However, if folks choose to make a few efficiency upgrades along with solar, their Return On Investment (ROI) can be substantially more significant. In addition to the major upgrades discussed below, there are also multiple smaller improvements a homeowner can make to further increase efficiency and savings.

Grid Tied Solar 101

Any amount of solar will directly reduce your electricity bill. Standard grid-tied solar works by offsetting energy consumption, which results in monthly savings. During the day, your meter “spins backwards”, and at night it “spins forward”. This is called net-metering. Think of the utility as a bank account. You deposit and withdraw energy from it each day, and only get billed for what you use. It is possible to produce enough power to essentially eliminate your entire bill; this is called going “net zero”.

The monetary benefits for solar energy come in a few ways. Each month that you are saving money on your bill (avoided cost of electricity) pushes you toward having received your initial investment back (referred to as the Return On Investment, or ROI). Premium solar panels can last well over 40 years, so if you “pay yourself back” in less time than that, you actually earn money on your solar panels for any time after the initial payback. In this area, typical ROI is 10-12 years. It’s important to note that any size grid-tied system up to the maximum required to net-zero your home will have a similar payback period, with larger systems providing a greater reward after full payback is obtained.  In fact, solar even works in winter (https://mtvsolar.com/does-solar-work-in-winter/)

Gas Appliance Upgrades

Many homes use gas to power just a handful of heating appliances. Rocky Mountain Institute found that over two-thirds of gas used in a house is for space heating—the rest is split between water heating, clothes drying, and cooking. Water heating, space heating and clothes drying are all available with high-efficiency heat pump technology. If households made this switch, they could reduce their annual carbon emissions by 25% or more.

The financial benefit can be surprisingly large. Because, yes, while getting off gas is great for the environment, it is also fantastic for a homeowner’s bank account. The savings start flowing in as soon as a household discontinues their gas service, as many states levy gas connections. In fact, the monthly fixed charge for a connection can be so high that discontinuing it saves a homeowner more than $300 per year—and that is not including the amount of gas that they actually purchased.

The challenge for households, when they choose to cut off their gas connection, is finding ways to complete all the jobs that gas used to power. While it is pretty straightforward to transition a home to all electric, these upgrades will require the purchase of new appliances. For many households, where old appliances are eating up both gas and electricity, this is a very natural transition as they slowly trade out old appliances for new, Energy Star versions.

About “old-skool” Electric Appliances

Standard resistance water heaters, clothes dryers, and cooktops waste large amounts of energy.  That old 1970s refrigerator in the garage?  You don’t really want to know!  Whereas with heat pump type appliances, you put fewer watts in and get even more BTUs out because they literally transfer heat from one place to another, rather than brute forcing the heating with a wire element.  Modern energy star refrigerators, window ACs, dishwashers and more are designed to use less energy and yet, do a better job than the ones of yesteryear.  The remainder of this article makes specific recommendations for upgrading your old gas or resistance electric appliances.

Clothes Drying

Ultrasonic dryers were co-developed through a partnership between the University of Florida, General Electric, and the Department of Energy. Instead of using heat, the dryer vibrates water out of fabric with sound waves, which produces a cool mist and allows fabric to be dried in half the amount of time it takes a traditional dryer. By looking at the market and energy usage, the Department of Energy found that over the course of a decade, if U.S. consumers adopted the ultrasonic dryer, they could save roughly $900 million in energy spending.

Another alternative is a heat pump dryer. This electric dryer option uses heat pump technology to generate the heat used for evaporating the water out of clothes and is ventless, meaning no air or heat is pushed out of the home. The dryer extracts the moisture as condensation via the internal recirculating heat pump technology.  Think of it as a big rotating dehumidifier for your clothes.


When it comes to cooking, electricity is a different story. Many consumers will hesitate about switching from gas to electric cooking—gas historically provides more control. And because of this desire to use gas for cooking, they will be reluctant to disconnect their gas. This can then have a snowball effect—if they are still paying for a gas connection, is it really worth it for them to convert their water and space heating systems to electric?

The good news is that there is a good alternative to gas cooking—electric induction cooking. These stoves heat food by creating an electric field with an electric coil. The electric field that these stoves create is unique because it does not heat the actual cooktop and the air around it—it only directly heats the cookware via high frequency electromagnetism. In other words, little energy is wasted, making it about 70% more efficient than both conventional electric and gas stoves. Additionally, because it delivers heat more quickly and it offers the user more control, it provides a cooking experience that is very much like a gas stove.

Water Heating

Heat pump water heaters are one of the best improvements in water heating in a long time. Rather than powering a heating element to heat the water the units use a small heat pump to do so using the same process that a central HVAC heat pump uses to heat your home. In fact, where an ordinary electric water heater can use 5000 watts of power during operation, a heat pump water heater can use less than 500 watts for the same job!

From Energy.gov, “Heat pump water heaters use electricity to move heat from one place to another instead of generating heat directly. Therefore, they can be two to three times more energy efficient than conventional electric resistance water heaters. To move the heat, heat pumps work like a refrigerator in reverse.”

While a quality electric or gas water heater starts around $500, a heat pump water heater runs around $1300. This price difference can be recuperated in just a few years, but if moving from a gas water heater to a heat pump water heater powered by the sun, the realization of ROI is very short.

The Small Things

Even little things like light bulbs add up.  Modern filament LED bulbs give the appearance of an incandescent bulb, but using a small fraction of the amount of energy.

Keeping the central heating turned down just a little, and using a personal space heater can save energy.  There are 300w desktop heaters readily available which will keep you toasty without using nearly as much power as cranking the central unit up.

The Elephant in the Room: HVAC

The Rocky Mountain Institute released a study that changes how individuals should invest in solar energy systems. The study looked at four cities across the U.S. Their goal was to analyze home electrification, both in terms of the financial costs and the carbon benefits.

The study found that in three of the four cities, if homes switched to electric heating it could help lower carbon emissions. The reason for this is that the electric grid in those cities is already clean enough. With solar, however, the situation gets far better.

Modern heat pumps are extremely efficient.  You can still get a simple single stage unit for not a lot of money and still be better off than with an old model, or you can get a two stage unit or even a variable speed compressor known as an “inverter heat pump”.  The variable speed ones are extremely efficient, with the highest SEER/HSPF ratings one can get.

Here is how the numbers break down: The average homeowner will save $24,900 over the course of 15 years, by switching to a high efficiency heat pump with solar —not to mention that carbon emissions can be reduced to zero. This means that even though a solar system and upgraded heat pump can be a $15,000 investment for a homeowner, they will still save nearly $10,000—and this does not include the Federal solar tax credit that homeowners currently get. It also does not include the fact that a solar energy system can power other appliances that used to run on natural gas (i.e. cooking, water heating, etc.).

In Summary

In short, an all-electric home can create substantial savings when it is done efficiently. The return on investment associated with a solar energy system, especially when combined with energy efficient appliance upgrades, surpasses $10,000 in less than two decades, as well as increasing the value of a home.

In the past, reducing carbon emissions was an expensive feat—dropping it down to zero was simply an impossibility. Now, however, with the advent of new appliances and the affordability of green energy, this goal is not only possible—it is also lucrative.
