  • Jun.19.2020 When to choose 60 cell vs. 72 cell panels

    If the only difference between 60- and 72-cell solar panels is their size, how do you choose one over the other?The ultimate decider is panel value, measured in cost-per-watt.Divide the price of the panel by the rated panel output (typically 250W-375W per panel). This will give you a baseline to compare panel value, regardless of size.Our advice is to go for the best cost-per-watt option that fits the space where you will install your system.Here’s an example. If your mounting space is 35’ wide and 10’ tall, you can only fit a row of 10 panels. You can install more power by using 72-cell panels because you have enough space to accommodate the taller panel size.

  • Jun.19.2020 5 Key Differences Between Lead acid and Lithium Batteries

    1. Cycle lifeWhen you discharge a battery (use it to power your appliances), then charge it back up with your panels, that is referred to as one charge cycle. We measure the lifespan of batteries not in terms of years, but rather how many cycles they can handle before they expire.Think of it like putting mileage on a car. When you evaluate the condition of a used car, mileage matters a lot more than the year it was produced.Same goes for batteries and the number of times they’ve been cycled. A sealed lead-acid battery at a vacation home may go through 100 cycles in 4 years, whereas the same battery might go through 300+ cycles in one year at a full-time residence. The one that has gone through 100 cycles is in much better shape.Cycle life is also a function of depth of discharge (how much capacity you use before recharging a battery). Deeper discharges put more stress on the battery, which shortens its cycle life.2. Depth of DischargeDischarge depth refers to how much overall capacity is used before recharging the battery. For example, if you use a quarter of your battery’s capacity, the depth of discharge would be 25%.Batteries don’t discharge fully when you use them. Instead, they have a recommended depth of discharge: how much can be used before they should be refilled.Lead-acid batteries should only be run to 50% depth of discharge. Beyond that point, you risk negatively affecting their lifespan.In contrast, lithium batteries can handle deep discharges of 80% or more. This essentially means they feature a higher usable capacity.3. EfficiencyLithium batteries are more efficient. This means that more of your solar power is stored and used.As an example, lead acid batteries are only 80-85% efficient depending on the model and condition. That means if you have 1,000 watts of solar coming into the batteries, there are only 800-850 watts available after the charging and discharging process.Lithium batteries are more than 95% efficient. In the same example, you’d have over 950 watts of power available.Higher efficiency means your batteries charge faster. Depending on the configuration of your system, it could also mean you buying fewer solar panels, less battery capacity and a smaller backup generator.4. Charge RateWith higher efficiency also comes a faster rate of charge for lithium batteries. They can handle a higher amperage from the charger, which means they can be refilled much faster than lead-acid.We express charge rate as a fraction, such as C/5, where C = the capacity of the battery in amp hours (Ah). So a 430 Ah battery charging at a rate of C/5 would receive 86 charging amps (430/5).Lead-acid batteries are limited in how much charge current they can handle, mainly because they will overheat if you charge them too quickly. In addition, the charge rate gets significantly slower as you approach full capacity.Lead acid batteries can charge around C/5 during the bulk phase (up to 85% capacity). After that, the battery charger automatically slows down to top off the batteries. This means lead acid batteries take longer to charge, in some cases more than 2x as long as a Lithium alternative.5. Energy DensityThe lead-acid batteries featured in the comparison above both weigh around 125 pounds. The lithium battery checks in at 192 pounds.Most installers can handle the extra weight, but DIYers might find the lithium batteries more challenging to install. It’s wise to enlist some help lifting and moving them into place.But that comes with a tradeoff: the energy density of lithium batteries is much higher than lead-acid, meaning they fit more storage capacity into less space.As you can see in the example, it takes two lithium batteries to power a 5.13 kW system, but you’d need 8 lead-acid batteries to do the same job. When you take the size of the entire battery bank into account, lithium weighs less than half as much.This can be a real benefit if you need to get creative with how you mount your battery bank. If you are hanging an enclosure on the wall or hiding it in a closet, the improved energy density helps your lithium battery bank fit into tighter spaces.

  • Jun.19.2020 How does solar work and the benefits of solar lighting

    As we have already hinted, the main principle of how solar lighting works is very simple. These lights collect solar energy and transform it into lighting—through a technology called the photovoltaic effect which is used in a solar panel. This effect collects solar energy. throughout the day and stores it in a rechargeable lithium ion battery that can be used later in the evening when there is no sunlight.Solar LED lights can be installed in many different areas. They offer amazing environmental benefits and can burnish a building owner’s green credentials, serve as a unique selling point for attracting and retaining tenants and help buildings or retrofits to quality as LEED points.
