10 Trends of Solar and Storage in 2021

10 Trends of Solar and Storage in 2021

While summarizing 2020, Barry Cinnamon said, “2020 was a year of continued awfulness, worse than we even said”. For companies in the solar system and energy storage industries, products and services concerning revenue were high in demand, and 2020 did not prove substandard. The need for inexpensive and reliable supplies could increase in 2021, considering long-term benefits at home working. 

Here are some of the predictions for solar and storage trends in 2021:

1. Roof Orientations for Solar System 

In the past 20 years, the module efficiency has increased 7% (from 13 to 20). Due to a 10x reduction in price and economic balance, installing modules on all unshaded roof orientations makes sense.

2. Carbon- Negative Buildings

The two-story buildings are designed in a carbon-negative way, call it generation of more energy than consumption, resulting in higher module efficiency. As a result, the percentage of rooftops covered with solar will fluctuate.

3. Escalation of Skill Levels for Solar and Storage Contractors

Higher skill levels are indispensable for integrated solar systems since the days are gone when installers connect a wire to operate a system. Today, installers need to be tricky with CAT 5/6 communication wiring, wireless communications protocols, desktop and cellphone users, and dozens of inverter/battery configuration features. Conventional training is only a stepping stone for solar and energy installers. 

4. Regulation of Module-Level Power Electronics

On 75% of the rooftop, Enphase (micro inventors) and SolarEdge (power optimizers) inventors install panels. However, the swift shutdown requirements on Patent protection, manufacturing scale, and National Electric Code have endangered a barrier to ingress competent products. Since technology is upgrading, it is crucial to keep up with innovative efforts to stay ahead.

5. Battery System Selection Criteria and Customer Service  

Batteries are generally short-lived. The 10-year warranties provided with all energy storage products are only as good as the financial and ethical integrity bracing the warranties. Hence, well-informed consumers will shop from the manufactures supporting their products.

6. A Requirement Stall for New Energy Storage Products

Before completing essential testing, the safety standards manage to prevent batteries from going into thermal runaway. Unfortunately, some don’t have a “pass-fail standard,” leaving the result up to individual jurisdictions. 

For instance, the banishment of batteries of 20 kilowatts or more in California since exit-way separation requirements fails to meet 36-inch batteries. 

7. Oversized Solar System at Rooftop

Building owners generally tend to install new electrical appliances when old ones fail, resulting in more electricity consumption, so oversizing the solar system is favorable.

8. EV Charger- A Common Option 

For new battery and solar installations, an EV charger is a common option. The standard solar system requires a 40-amp back feed circuit that can also be applicable for a level 2 electric vehicle charger. This would not only reduce cost but also simplify wiring, permitting, and controls for EV charging.

9. Future in Favour of Two Batteries in Every Garage

One battery is in the EV, while one stationary battery is attached to the wall. The continued cost declination for solar-connected stationary batteries will move the manufacturers towards vehicle-to-grid systems. 

The efficient hack is the separate battery system for the home along with the battery in the car.

10. Entire Home Battery Backup Is Expensive

Innovation of new smart load shedding electrical panels seems ideal for new-build home construction. Retrofit installations served with standalone load-shedding controllers preferably combined with popular inverter systems. 

For solar and storage in the white house, another good year for solar and storage is likely in the US. The two factors and hurdle to limit the market penetration for cost-effective systems are downright malice among incumbent utilities resulting in complex interconnection requirements. The other is fluctuating onerous soft costs associated with standard and building codes.
