Comparing residential solar and battery installers with clear local service and long-term reliability is often confusing in San Antonio. Many providers avoid publishing project pricing and do not guarantee local service or single-team project management. This comparison covers service area, installation options, and warranties across four providers so you can match the right installer to your property and support expectations.

Alpha solar solutions
At a glance
Alpha Solar Solutions offers on-site battery integration with Tesla Powerwall, Enphase IQ Batteries, and SolarEdge Energy Bank for homes in San Antonio. The company pairs rooftop arrays with battery backups and EV charger installs. Alphasolarsa reports a 25 year warranty on its panels. That warranty and the local focus target long term reliability for homeowners.
Core features
Alpha Solar Solutions delivers custom system design tailored to each property and energy needs. The service includes professional installation, ongoing system monitoring, and regular maintenance. Battery backup options are available and can be combined with EV charger installation. The company also performs solar panel cleaning and panel detach and reattachment for roof work.
Key differentiator
The main difference is local, property specific design backed by full lifecycle support. Alphasolarsa designs the array to match roof, shade, and household load. The team then installs, monitors, and maintains the system so the homeowner has one local point of contact for service and backup power needs.
Pros
-
Local installation team with hands on experience in San Antonio. They know local permitting, weather patterns, and utility interconnection processes.
-
25 year warranty on panels provides a long term protection period. That warranty reduces ownership risk compared with shorter guarantees.
-
Offers combined services from design through maintenance. You get system monitoring, cleaning, and post install support from the same provider.
-
Supports major battery brands so you can add backup power for outages and peak shaving. This makes the system useful during summer grid stress.
-
Includes EV charger installation which simplifies adding vehicle charging to a new solar and battery setup.
Cons
- Primarily serves San Antonio and nearby areas, which limits availability outside that region.
Notable integrations
- Tesla Powerwall
- Enphase IQ Batteries
- SolarEdge Energy Bank
Who it’s for
This offering fits San Antonio homeowners and small to medium sized business owners who want energy independence and outage protection. It also suits property developers adding solar to new or existing projects. If you value local support and a single vendor for design, install, and maintenance this is a practical match.
Unique value proposition
The company backs installations with a 25 year warranty on panels while supporting multiple battery platforms. That combination reduces replacement risk and keeps options open for battery selection. For a homeowner, that means predictable long term coverage and flexibility to choose the backup hardware that fits their needs.
Real world use case
A San Antonio homeowner replaces a high summer electric bill with a rooftop array sized to their usage and a paired battery for nighttime backup. The installer handles permitting, installs a compatible battery, and sets up monitoring. Regular cleaning and maintenance help maintain expected output while the homeowner gains outage resilience.
Pricing
Pricing is not published and is informational only in the company materials. Project cost depends on system size, battery choice, and site specifics such as roof type and shade. Alphasolarsa provides custom quotes after on site evaluation and energy review.

Big sun solar
At a glance
Big Sun Solar reports an 88 NPS score and 5-star ratings in its materials. That claim signals strong vendor-reported satisfaction for commercial clients. The company focuses on Texas projects and handled one of the largest municipal onsite solar efforts in San Antonio. Its teams manage design, engineering, permitting, installation, and maintenance internally.
Core features
- Turnkey commercial solar installations tailored to client goals, from initial site assessment to final commissioning.
- Energy storage systems and battery options sized for demand and backup needs.
- Customized design backed by internal engineering teams familiar with regional utility rules.
- Full project lifecycle management including permits, utility interconnection, and incentives support.
- Resources and guidance on local incentives and energy efficiency as part of project planning.
Key differentiator
Big Sun Solar runs every phase internally, which reduces handoffs between vendors. That internal control gives clients one team to contact for design questions, permitting delays, and long term maintenance. For Texas organizations that value local regulatory experience, this single-team approach shortens coordination and keeps technical accountability clear.
Pros
-
Internal project management reduces coordination overhead. One team handles engineering, permitting, and installation, so you deal with fewer vendors.
-
Deep Texas focus. Staff familiarity with state and local utility rules speeds interconnection and incentive work for San Antonio area projects.
-
Proven municipal experience. The vendor materials cite large public sector projects that show capacity for high scale work.
-
The vendor reports strong customer feedback. That NPS figure above and listed 5-star ratings suggest clients are generally satisfied.
-
Active local involvement. The company highlights workforce and community development as part of project scope.
Cons
-
No third-party review set. Publicly available independent reviews or audits are not provided in the sourced content.
-
Pricing transparency is limited. Detailed cost breakdowns and sample quotes are not published in the source material.
-
Geographic scope unclear. The product information focuses on Texas, and capabilities outside the state are not specified.
When it may not fit
If you need publicly verifiable third-party reviews before a procurement decision, this offering may not meet that requirement. Organizations outside Texas should confirm local availability and support, as the company emphasizes regional projects. If you require published sample pricing for budget planning, expect to request a custom quote instead.
Who it’s for
Businesses, municipalities, and nonprofits in Texas that want a single vendor to manage commercial solar and storage projects will find this a good match. Procurement teams that value local regulatory knowledge and a single technical contact benefit most. Organizations needing published pricing or national coverage should look elsewhere.
Real world use case
San Antonio’s city government partnered with Big Sun Solar on a large municipal onsite solar project. The engagement combined rooftop and ground arrays with battery systems to reduce operating costs and boost resilience for municipal facilities. The case shows how the vendor coordinates permits, interconnection, and long term maintenance for public sector projects.
Pricing
Public pricing is not listed. Big Sun Solar offers custom project quotes based on site size, load profile, and storage needs. Expect pricing to be delivered as a tailored proposal after site evaluation and feasibility work.

SolarEdge
At a glance
According to the company, SolarEdge reports over 5,000 installations and a 4.9-star Google rating. They operate in San Antonio and focus on in-house installation and transparent pricing. The local offering covers rooftop, ground mount, carport, and patio systems plus batteries and maintenance.
Core features
-
Residential and commercial solar installation services for single-family homes and businesses. Installation types include rooftop, ground mount, carport, and patio setups.
-
Battery backup systems compatible with Tesla and Enphase batteries for outage protection. Battery work is offered alongside solar design and installation.
-
Panel maintenance, inverter repair, and ongoing service to keep systems online. The company advertises dedicated maintenance as part of its local service model.
-
In-house professional installation backed by a 30-year workmanship warranty and local crews. That setup reduces subcontractor handoffs and centralizes responsibility.
Key differentiator
SolarEdge pairs on-site crews with a long workmanship guarantee. Their claim of a 30-year workmanship warranty stands out for buyers who want a single company responsible for installation and follow-up. The offering also emphasizes multiple backup power choices to match Texas outage risk and varying property types.
Pros
-
Helpful technical support staff and knowledgeable representatives. The company uses chat and direct support channels for questions.
-
Clear and transparent pricing with no hidden fees, according to customer reports. That clarity simplifies comparing quotes for San Antonio homeowners.
-
In-house installation ensures one team owns the project from permit to commissioning. This reduces coordination gaps that sometimes occur with subcontracted work.
-
Diverse solar and backup options fit different roof types and businesses. The installer supports rooftop, ground mount, carport, and patio configurations.
-
The company reports a strong local track record; see the figure above for reported installation volume and rating. That reported footprint suggests local experience with Texas permit and utility processes.
Cons
-
Frequent hardware failures have been reported for some inverters and optimizers, affecting reliability for certain customers.
-
Some users describe slower support response times and difficulty reaching representatives after installation. Delayed responses can extend downtime.
-
Unreliable power optimizers have caused service disruptions for a subset of customers. Optimizer issues often require part replacement and technician visits.
-
Post-installation follow-up and ongoing support can be inconsistent across projects, based on user feedback.
When it may not fit
SolarEdge is not a match for homeowners who want a do-it-yourself solution or minimal ongoing support. Buyers who need guaranteed zero downtime may prefer vendors with different hardware records. If you plan to self-install or want a strictly parts-only vendor relationship, this company will likely feel too hands-on.
Who it’s for
This provider fits Texas property owners who prefer a local crew to handle permits, installation, and long-term service. San Antonio homeowners seeking professional installs with long warranties will find the model appealing. Business owners who want combined solar and backup installations also match the service profile.
Real world use case
According to the company, a San Antonio family installed rooftop solar with battery backup and cut their electric bill by 30–40 percent. That outcome illustrates how a combined solar and battery setup can reduce bills and improve resilience during summer outages. The local crew handled permitting, install, and a follow-up maintenance check.
Pricing
Pricing depends on system size and project scope. Request a free quote for precise costs and a site assessment. Residential and commercial quotes reflect different design and permitting needs, so expect tailored proposals.

When it may not fit
If you want a provider with extensive independent reviews and broad national rating coverage, this company may feel short on third party evidence.

Real world use case
A San Antonio farm installs a custom off grid solar and battery system to keep irrigation and pumps running during storms. South Texas Solar Systems Inc. sized the array and battery, handled permits, and schedules seasonal cleaning to keep output steady. The farm moves from intermittent grid reliance to predictable local generation.
Pricing
Not applicable for public listing. The vendor presents projects as custom quotes rather than fixed packages. They also advertise financing options and access to tax credits and rebates to lower upfront cost.
