Does a solar company qualify?
- Product startups (software or hardware you sell) qualify for Activate. Agencies, consultancies and dev shops that bill by the hour usually don't, unless they're building their own product.
- Your company is usually under 10 years old, pre-Series B for the Provider tier, and hasn't had Activate credits before.
- Past the startup stage? Established solar companies can look at business and migration funding instead.
- Nonprofit or researcher? The AWS Imagine Grant and Cloud Credit for Research are separate from Activate.

Where solar startups burn credits fastest
Per-message IoT costs at high frequency
Sending sensor readings every second instead of every minute multiplies IoT Core messaging cost 60x.
Fix: Batch readings at the edge with Greengrass and send aggregated messages.
Simulations on on-demand instances
Grid, weather and battery models run for hours on large instances.
Fix: Use AWS Batch with Spot; most simulations restart cleanly.
Downloading open data you can query in place
Copying public satellite or climate datasets into your account adds storage and transfer.
Fix: Use the Registry of Open Data on AWS directly from S3 in the same region.
Time-series in a relational database
Storing billions of sensor rows in RDS needs large instances.
Fix: Use Timestream for LiveAnalytics or partitioned Parquet in S3.
NAT Gateway data charges
Every private subnet sending traffic to the internet through a NAT Gateway pays about $0.045 per GB on top of the hourly fee. Pulling container images or calling third-party APIs from private subnets adds up fast.
Fix: Use VPC endpoints for S3, ECR and DynamoDB, and keep chatty services in public subnets behind security groups where it is safe.
Unbounded CloudWatch logs
Debug-level logs from every request are ingested at about $0.50 per GB and kept forever by default.
Fix: Set log retention to 14 or 30 days and lower log levels in production.

AWS vs Google Cloud vs Azure for solar
AWS Activate
$1,000 to $100,000+
Widest service range, largest partner and provider network
Google for Startups Cloud
Up to $200,000 ($350,000 for AI)
BigQuery, Vertex AI and Gemini
Microsoft for Startups
Up to $150,000 Azure
Azure OpenAI, Microsoft 365 and enterprise sales channels
All three have sustainability programmes; Google and AWS both publish carbon data per region.
Ceilings are programme maximums and change often. Check each provider before applying.
Rules and gotchas for solar
- Separate climate credit programmes exist
- AWS has run sustainability-focused programmes alongside Activate; check for open calls before applying to standard Activate.
- Utility and grid data may be critical infrastructure
- Grid operators can require specific security certifications and data location.
- Hardware isn't covered
- Credits pay for AWS services only, not meters, sensors or connectivity.

Questions
Is there a special AWS credit programme for solar startups?
Yes: Clean Energy Accelerator 4.0 (Up to $100k; up to $300k for foundation-model builders; Open enrollment). Standard AWS Activate also applies.
How much in AWS credits can a solar startup get?
The largest pot is Clean Energy Accelerator 4.0: Up to $100k; up to $300k for foundation-model builders. Otherwise Activate gives up to $200,000 through a provider.
Do AWS credits cover what a solar product runs on?
Usually yes. A typical setup (IoT Core for sensor and grid data, Timestream or S3 for time series, SageMaker for forecasting) is covered by promotional credits. Marketplace purchases, support plans and taxes are not.
How long will credits last for a solar startup?
At about $400/month (MVP), $25,000 lasts around 63 months, though credits usually expire after 12 to 24 months.
What if AWS rejects my solar application?
Try a different route: an Activate Provider, another niche programme, Google for Startups Accelerator: Climate Change or Microsoft for Startups Founders Hub, or our partner match.
