How to Write RFPs for Municipal Solar Street Lights

Practical Guide to Procuring Solar Street Lighting for Cities

Define project objectives and scope for Municipal Solar Street Light procurement

Clear objectives are the foundation of any Request for Proposal (RFP). For Municipal Solar Street Light projects, define specific goals such as reducing grid energy consumption, improving nighttime safety, accelerating net-zero targets, or deploying off-grid lighting in remote areas. Specify the number of luminaires, average mounting height, target illuminance (lux), and the geographic and climatic conditions (solar irradiation, temperature ranges, prevailing wind). Include keywords like Municipal Solar Street Light and emphasize evaluation for total-cost-of-ownership (TCO) and local maintenance capability.

List essential technical specifications for Municipal Solar Street Light systems

RFPs must contain precise, measurable technical requirements. Include:

• Nominal LED lumen output and efficacy (lm/W) at rated current.
• Solar PV module specifications: STC power (W), Pmax temperature coefficient, panel efficiency, and IP rating.
• Battery type, nominal capacity (Wh), depth-of-discharge limit, cycle life, and temperature performance.
• Controller/MPPT specification, maximum charge/discharge current, and intelligent dimming/scheduling features.
• Pole, bracket, and foundation design loads (wind speed and soil conditions) and anti-vandalism measures.
• Ingress protection (IP65+), luminaire corrosion class (e.g., C5), and surge protection (e.g., 10kV/5kA or per local grid conditions).

Require suppliers to provide photometric files (IES or LDT), product datasheets, and results from standardized tests (LM-79/LM-80 where applicable) so performance claims are verifiable.

Specify performance metrics and verification for Municipal Solar Street Light proposals

Define measurable acceptance criteria and on-site commissioning tests. Typical metrics to request include:

• Average horizontal illuminance (lux) and uniformity ratio (max/min).
• System autonomy days (number of consecutive cloudy days the luminaire will operate at nominal schedule without solar input).
• Battery state-of-health reporting and projected end-of-life capacity (e.g., >70% after 5 years).
• Expected lumen maintenance (e.g., L70 at 50,000 hours) with supporting LM-80 reports and TM-21 extrapolation.
• Cold-start performance at minimum ambient temperature.

Include third-party test or factory acceptance requirements (TÜV/UL/SGS reports). Require vendors to install data loggers for the first 6–12 months to record energy generation, consumption, and battery performance for validation.

Include contractual terms, warranties, and service levels for Municipal Solar Street Light projects

Robust contractual terms protect the municipality and ensure long-term performance. Specify minimum warranty periods and service level agreements (SLAs):

• Product warranty: typically 3–5 years for whole units, 5–10 years for PV modules, and 3–8 years for batteries depending on chemistry.
• Performance warranty: defined minimum energy generation or autonomy days and lumen maintenance guarantees.
• Response times: fault-response (e.g., 48–72 hours for urban centers), repair or replace timeframes, and spare parts availability.
• Penalties and liquidated damages for missed milestones or underperformance.

Also address transfer of ownership, training of municipal maintenance teams, and documentation delivery (as-built drawings, O&M manuals, and spare-parts kits).

Set evaluation criteria and scoring to compare Municipal Solar Street Light bids

Create a weighted evaluation matrix that balances technical merit, lifecycle cost, vendor experience, and local value. A sample scoring rubric (weights are illustrative):

• Technical compliance: 30%
• Lifecycle cost (TCO) and financing: 25%
• Warranty, SLA & maintenance plan: 15%
• Project timeline and implementation capacity: 10%
• Local content / training and community engagement: 10%
• References and proven track record: 10%

Require proposers to submit references for at least three municipal deployments and provide contactable references as part of technical evaluation.

Prepare a lifecycle cost analysis table for Municipal Solar Street Light options

Municipal buyers must compare upfront capital cost vs. 10–20 year lifecycle costs (energy, O&M, replacements). Provide a comparative example table in the RFP and ask bidders to submit a comparable TCO table based on the municipality’s assumptions. Example (assumptions noted):

Notes: numbers are illustrative — ask bidders to run NPV on lifecycle costs using a municipality-specific discount rate. Cite renewable cost declines (see references) when assessing PV and battery pricing trends.

Define implementation schedule, commissioning, and training requirements for Municipal Solar Street Light works

Include a detailed project timeline in the RFP: procurement, manufacturing, delivery, civil works, installation, commissioning, and a warranty-monitoring period. Require vendors to provide commissioning checklists and training modules for municipal crews covering routine checks, battery replacement protocols, and remote-monitoring dashboards. For urban rollouts, require traffic management and public-safety plans during installation.

Mandate compliance, standards, and certifications for Municipal Solar Street Light equipment

Require compliance with national and international standards. Typical certifications to request include:

• ISO 9001 quality management (vendor factory).
• CE marking (where applicable), UL/ETL for electrical safety, and BIS for India projects.
• TÜV or third-party test reports for PV modules and batteries.
• IP and IK ratings for ingress and impact protection (e.g., IP65, IK08).

Ask bidders to include copies of certificates and laboratory test reports. Require factory acceptance tests (FAT) witnessed by the municipality or an independent verifier.

List questions and documentation to request from vendors for Municipal Solar Street Light evaluation

To make vendor comparisons robust, ask for:

• Detailed Bill of Materials (BOM) and manufacturer datasheets.
• Photometric studies (IES files) and light distribution plans for proposed spacing.
• Battery chemistry and expected cycle life with test data.
• Remote monitoring and IoT capabilities, data access rights, and cybersecurity measures.
• Insurance, guarantees, and decommissioning/disposal plans for batteries and PV modules.

Require a site survey and geospatial plan as part of the technical proposal; proposals lacking an on-site assessment should score lower.

Provide a sample RFP structure and required attachments for Municipal Solar Street Light projects

Offer a clear outline that municipalities can adapt. A practical RFP structure includes:

1. Project overview and objectives.
2. Scope of work and deliverables (product, installation, commissioning, training).
3. Technical specifications and performance criteria.
4. Commercial terms, payment schedule, and evaluation criteria.
5. Warranty and SLA requirements.
6. Submission instructions and evaluation timetable.
7. Attachments: site maps, photometric requirements, sample contract, and vendor questionnaire.

Provide templates for evaluation scoring and TCO calculation to ensure apples-to-apples comparisons.
