When the grid goes off, the power stays on
In this clip from a real installation, the installer switches the grid off. The bedroom's light, fan and air conditioner keep running on solar alone, with no battery.
For homeownersSolar that keeps going
Solar that keeps going
when the sky doesn't cooperate
A cloud, a chimney shadow, a leaf on one panel: on a conventional system, the whole string slows down. With Sparq, each panel works on its own, and the rest keep producing.
How it works
What actually happens on your roof
From shade to system monitoring, see how the Quad puts each panel to work for your home.
One panel in shade, three keep working
A cloud, a chimney's shadow, a leaf on one corner of the roof, with independent MPPT per panel, that panel's output drops and the other three keep producing at full rate. Against a one-per-panel microinverter, per-panel shade tolerance is a tie, both track every panel independently. The Quad's advantage is that one unit does the job of four, at a lower installed cost. Over a year, that can mean more energy harvested from the same roof.
The grid goes down, your lights don't
Dual-mode operation lets the system keep producing for the loads in your home during a grid outage, without a battery. A conventional grid-tied string inverter is designed to shut off the moment the grid does. The house above stays lit because its own panel never depended on that line.
No electrolytic capacitors
Electrolytic capacitors are a common wear item in power electronics. The Quad is built without them and without fans, using long-life components matched to the panels' 25-year design life, with a 12-year standard warranty behind it. The dashed outline above is what a normal board would have there. It isn't a stronger part. It's the absent one.
Safer by construction
All-AC cabling with inherent Rapid Shutdown compliance. No high-voltage DC on the roof. Each Quad converts solar power to AC at the panels, keeping DC connections short and local.
You see the panel, not just the total
SparqVu and the SparqSync app report at panel level: energy, grid voltage, per-inverter detail. If one of the four channels on a unit dips, you see which one, not just that the day's total looks a little low.

Questions homeowners ask
The questions we hear from homeowners
The answers a household asks for, from the site's FAQ. Every question, the installers' and the commercial ones too, is on the resources page.
Solar at home
A typical home solar system includes the following:
- Solar Panels: Convert sunlight into direct current (DC) electricity
- Inverter (Micro or String): Converts DC electricity into alternating current (AC) for home use.
- Junction Box: A protective enclosure where electrical wires connect.
- Gateway (Monitoring Device): Communicates with inverters and lets homeowners track system performance.
- Disconnect Switch (AC/DC): Manually shuts down power during maintenance or emergencies.
- Trunk Cable: Main cable connecting multiple microinverters or panel circuits.
- Branch Cable: Secondary cable connecting panel groups to the trunk cable.
- Mounting Structure: Hardware used to securely fasten panels to the roof or ground.
- Battery (Optional): Stores excess energy for use at night or during outages.
System cost depends on size, equipment, labor, and region. Incentives like tax credits can significantly reduce the final price.
Most roofs are suitable if they're structurally sound, get enough sunlight, and have minimal shading. A professional assessment will confirm suitability.
Many homeowners lower their bills. Savings depend on system size, usage habits, and electricity rates.
Federal tax credits, local utility rebates, and renewable energy grants may be available. Check your local and national programs.
Several online tools can help you assess the feasibility, cost, and savings of a solar system for your home. Here's a short list of tools we find useful:
- Google Project Sunroof (https://sunroof.withgoogle.com/): Uses satellite imagery to analyze roof size, shading, and local climate.
- PVWatts Calculator (https://pvwatts.nrel.gov/): Offers a detailed estimate of system output based on location, system size, tilt, and more.
- EnergySage Solar Calculator (https://www.energysage.com/solar/calculator/): Estimates optimal system size, cost, and savings based on utility rates and location.
- Solar-Estimate (https://www.solar-estimate.org/): Provides system sizing, savings projections, and can match homeowners with installers.
A typical residential installation takes 1-3 days, but the full process - including design, permitting, and approvals - can take several weeks.
It is not required, but batteries store energy for backup and off-grid use. Without one, excess energy is sent to the grid.
Solar PV systems are generally low maintenance, but upkeep depends on the system type and the long-term reliability of its components. Panels may require occasional cleaning to remove dirt, dust, or debris, especially in dry or dusty areas. An annual inspection is recommended to check for issues with wiring, mounting hardware, or performance drops. One of the most common maintenance concerns involves the failure of electrolytic capacitors - key components in inverters - which typically have a lifespan of 10-12 years, depending on heat, usage, and environmental conditions. Choosing high-quality inverters and components can help minimize long-term maintenance needs and improve overall system reliability.
Typically, 25-30 years. Most come with performance warranties and degrade very slowly over time.
Yes. Owned solar systems can increase resale value and appeal to buyers. Leased systems may require transfer agreements.
You can transfer ownership of the solar system if it's leased or financed. Owned systems generally enhance property value.
The terms
A billing system that credits solar owners for excess electricity sent to the grid. These credits can offset your consumption at night or on cloudy days.
A system that can function both with the grid (supplying/consuming power) and independently (during outages). A Sparq dual-mode system can keep powering local loads in an outage without a battery.
A technology in inverters that continuously adjusts electrical parameters to extract the maximum possible power from solar panels under varying sunlight conditions.
A safety mechanism that quickly shuts down power at the panel level during emergencies or for maintenance, meeting electrical code requirements.
Quad2
The Sparq Quad 2000 is a high-efficiency microinverter supporting up to four PV module inputs, each with independent MPPT. It simplifies wiring with a single AC trunk output. Its key features include dual-mode operation (grid-tied and off-grid), high power density, a modular design, and panel-level system monitoring via SparqVu and SparqSync.
Yes, the Quad2000 integrates with SparqVu to provide panel-level performance tracking, remote diagnostics, and system alerts.
Yes. The Sparq app is available for iOS and Android for remote monitoring and notifications.
Firmware updates are automatic and over-the-air via the Sparq Gateway, provided the system is connected to the internet.
Yes. Off-grid mode is supported and can be enabled via the Sparq Gateway.

Carbon and pricing
Carbon intensity refers to the amount of carbon dioxide (CO2) emissions produced per unit of electricity generated. It is typically measured in grams of CO2 per kilowatt-hour (g CO2/kWh). The carbon intensity can vary depending on the energy mix used by your local electricity grid (e.g., coal, natural gas, nuclear, or renewable energy sources like wind or solar).
In the SPARQ User App, carbon intensity is used to calculate the reduction in CO2 emissions due to your solar plant. By producing your own solar energy, you reduce the need for electricity from the grid, thus lowering overall CO2 emissions. To accurately calculate this reduction, the app requires you to input the carbon intensity value for your region.
You can find the carbon intensity for your area by checking with your local electricity provider or using online resources that track carbon intensity by region.
Electricity unit price refers to the cost you pay per kilowatt-hour (kWh) of electricity consumed from the grid. This price can vary based on your electricity provider, the time of day, and the type of plan you're on (e.g., fixed, variable, or time-of-use pricing).
Installers
Yes. Sparq Systems provides a fully AC-based system, eliminating the need for high-voltage DC cabling. This simplifies installation and enhances installer and homeowner safety.
Warranty and service
Sparq offers a standard 12-year warranty, which can be extended up to 25 years. Installers should register the system and advise customers to keep records for any future claims.
