Solar Shines on the Hill Day 2019: Recap

This week, I had the opportunity to join the Solar Energy Industries Association (SEIA) for their Solar Shines on the Hill Day.  The event is a great opportunity to show up in force in Washington DC in support of the solar industry, talking about how the solar jobs that exist throughout the country, and the financial and environmental benefits that home- and business-owners experience from solar in every state. Here’s a quick recap of what we spoke about and what we learned.

Comparing lithium-ion battery chemistries

Lithium-ion batteries are the most popular products used for solar electricity storage today. Within the umbrella category of lithium-ion batteries, there are several specific chemistries that battery manufacturers employ in their products. These chemistries each have their own advantages and disadvantages, as well as ideal use cases.

Air source heat pumps vs. geothermal heat pumps

Did you know that you can both heat your home in the dead of winter and cool things down during the hottest day of the summer using the same system? Heat pumps are a highly efficient technology that serves the dual purpose of both heating and cooling spaces. But like other types of thermal technology, there are a variety of heat pumps to consider, and some may be better suited for you depending on your property, preferences, and heating and cooling needs. In this article, we’ll discuss the major differences between the two major types of heat pumps: air source heat pumps and ground source/geothermal heat pumps.

Battery warranties: what you need to know

Similar to your laptop or cell phone battery, solar batteries degrade over time: as you continue to use and charge your battery, it loses the ability to hold a charge. Fortunately, solar battery manufacturers provide warranties that guarantee the performance of a battery to a certain level. In this article, we’ll dive into what matters in a solar battery warranty, and how some of the top solar batteries – Tesla Powerwall 2, LG Chem RESU 10H, and sonnen eco – stack up.

home with solar panels and a battery

Does solar-plus-storage still work during an outage?

Battery storage paired with solar panels is a great way to save money on electricity bills in the long term, especially with new rate plans like time-of-use becoming more prevalent. But does adding a battery mean you’ll be able to produce, store, and use electricity with solar when the grid is down? Do you even need a battery? In this article, we’ll dissect how solar and storage can make for an effective grid resiliency technique.

An overview of Lumin’s energy management system

When thinking about installing a solar or a solar-plus-storage system at your home or business, there’s one piece of information that is of the utmost importance: how much electricity do you use, and which of your home appliances use that electricity. That’s exactly where Lumin can help: the three-year-old, Charlottesville, Virginia-based company is joining the relatively nascent field of creating smart circuits, allowing you to dynamically choose or automate what to power with your solar and storage, which is especially useful in the event of an outage.
