Based on our bottom-up modeling, the Q1 2021 PV and energy storage cost benchmarks are: $2.65 per watt DC (WDC) (or $3.05/WAC) for residential PV systems, 1.56/WDC (or $1.79/WAC) for commercial rooftop PV systems, $1.64/WDC (or $1.88/WAC) for commercial ground-mount PV systems, $0.83/WDC (or $1.13/WAC) for fixed-tilt utility-scale PV systems, $0.89/WDC (or $1.20/WAC) for one-axis-tracking utility-scale PV systems, $30,326-$33,618 for a 7.15-kWDC residential PV system with 5 kW/12.5 kWh nameplate of storage, $2.04 - $2.10 million for a 1-MWDC commercial ground-mount PV system colocated with 600 kW/2.4 MWhusable of storage, $166 - $167 million for a 100-MWDC one-axis tracker PV system colocated with 60 MW/240 MWhusable of storage.

The benchmarks in this report are bottom-up cost estimates of all major inputs to PV and energy storage system (ESS) installations. Bottom-up costs are based on national averages and do not necessarily represent typical costs in all local markets.
Non-battery systems, on the other hand, range considerably more depending on duration. Looking at 100 MW systems, at a 2-hour duration, gravity-based energy storage is estimated to be over $1,100/kWh but drops to approximately $200/kWh at 100 hours.
The cost estimates provided in the report are not intended to be exact numbers but reflect a representative cost based on ranges provided by various sources for the examined technologies. The analysis was done for energy storage systems (ESSs) across various power levels and energy-to-power ratios.
Cost metrics are approached from the viewpoint of the final downstream entity in the energy storage project, ultimately representing the final project cost. This framework helps eliminate current inconsistencies associated with specific cost categories (e.g., energy storage racks vs. energy storage modules).
The cost categories used in the report extend across all energy storage technologies to allow ease of data comparison. Direct costs correspond to equipment capital and installation, while indirect costs include EPC fee and project development, which include permitting, preliminary engineering design, and the owner’s engineer and financing costs.
Additionally, given their long calendar life, decommissioning costs are considered to be very small on a present value basis. Thermal energy storage also benefits from easy recyclability of power equipment and for most of the thermal SB. For these reasons, decommissioning costs are not considered in this analysis.

Every home, climate and property are different. Use this checklist as a general guide to winter home maintenance and add items that are unique to your property such as draining the swimming pool, cutting firewood or stocking up on pellet stove fuel. For new homeowners, we suggest using each season to help you prepare for next year.
The first step to maximizing your battery storage system for cold weather is to locate it in a place protected from the elements, such as a garage, house, or insulated building. Keeping the batteries in an insulated area ensures you maximize their performance, even if the temperatures outside are dropping.
Maintaining a home in the winter with a busy schedule is a big task. If you need help or you need a home repair, just give Mr. Handyman a call. We can help seal drafty windows or make any necessary repairs to help you keep your home in great shape. Give us a call or request an appointment online. Get your home winter-ready!
Monitor windows and doors for drafts. During deep cold spells (less than 15 degrees for more than 24 hours) keep all interior doors open to encourage heat circulation. Replace your HVAC air filter every three months. Since keeping our homes warm and cozy in the winter is a priority, why not make it easier and less expensive?
It’s easy to forget, or ignore, the importance of preparing your house for winter. Staying cozy inside your home sounds a lot better than bundling up to brave the cold or checking off a to-do list. However, maintaining your home during the winter will help you avoid expensive repairs or surprises.
A programable thermostat is a simple way to save on heating costs if set up properly. Use the programs to automatically turn the heat down when you’re not at home or sleeping. You can even control smart thermostats from your phone or use an app to monitor energy usage. Maintaining a home in the winter with a busy schedule is a big task.
